Like any medication these prilosec facet effects vary in their severity and what might be delicate to at least one person might result in a a lot of serious reaction in others. If you are doing get any of those prilosec side effects then it's terribly important that you contact your doctor while doable before they perhaps start to harm your health in different ways that. prilosec side effects long termMustard Gas

Mustard Gas(1,5-dichloro-3-thiapentane) or H, yprite, sulfur mustard, Kampstoff Lost, the most successful poison gas in World War One,is a chemical warfare agent which got its name from the odor of the impure version which smells like mustard, garlic or horseradish ( however in its pure form in it colourless and odorless).Sulfur mustard is an organic compound portrayed by the formula (ClCH2CH2)2S and its class is related to cytotoxic, vesicant chemical warfare agents. There are many methods in which sulfur mustard is synthesized including that of the Depretz ( shown in the synthesis diagram below), Meyer, Meyer-Clarke Method. Chemically speaking mustard gas is a simple "thioether" or sulfide

Mustard gas is an extremely detrimental gas, with symptoms lying dormant in the body for over 2 weeks, the reason for this being that mustard gas is not very soluble in water but it is in fat and therefore it would take a longer amount of time to travel through the body. It's component's ability to bond to the guanine nucleotide in DNA makes mustard gas particular harmful to cellular health, with severe cases of over exposure leading to mass cellular death or even cancer.

The physiological effects are a wide variety due to mustard gas's unique ability to bond to guanine or alkalizing property. Many of the side effects/consequences range from blisters to fatal 3rd degree burns. The most common effects of mustard gas have to to with prolonged exposure to open areas of skin such as: debilitating chemical burns, blisters, conjunctivitis, miosis ( not meiosis). Also when inhaled it can lead to serious respiratory issues by damaging mucous membranes and causing pulmonary edema.

The Figure to the right shows that synthesis of mustard gas beginning with 1 Sulfur atom (S) and 2 Chlorine atoms (Cl) being added to 2 Hydrogen (H) quadruple bonds. (* oops the 2 represents 2 carbon plus 4 hydrogen)

Mustard gas was first synthesized and characterized by the German Fredrick Gunthrie in 1860, however it is suspected that mustard was possibly developed as early as 1822 by M. Depretz. Mustard gas' first use was in July of 1917 when German soldiers used mustard gas against British soldiers during World War 1. The Germans had secretly been engineering them and the Allied Powers did not being to use mustard gas till the November of 1917. Mustard gas was utilized buy spraying it as an aerosol (mixed with other chemicals of course) it was also dispersed from aerosol bombs, land mines artillery shells and rockets. Only about 1 % of the cases were fatal, however, killing was not its purpose; its purpose was to incapacitate its enemies and keep them in their trenches while the opposition could muster air strikes.

The following videos are a series of videos on the battle of Yprise and the fist release of mustard gas:

Sadly there are not many other other recorded/ feasible ways in which to utilize mustard besides that of chemical warfare, furthermore there is no record of mustard gas morally benefiting human advancement either. Although some could argue that, practically speaking, mustard gas advanced the field of chemical weaponry and modern technology as it increased the knowledge of atom manipulation and was a helpful deterrent of the opposing enemy. However there is an ironic usage to mustard gas. Mustard gas has been known to cause cancer but ironically enough i can also be used to help cure it! Research in 1946 concluded that a variation of mustard gas nitrogen mustard reduced the size of a mice tumors from that experiment of nitrogen mustard has been implemented in many of the modern cancer fighting drugs and is mainly being used to cure cancer of the lymph glands.

The controversy is that though through the discovery of mustard gas people have found a way to fight cancer, one can still not help thinking about those who suffered die to the gas. Morally, there is the same question: how many people should suffer for the "greater good". Many of those persons exposed to the mustard gas suffered terribly painful injuries and for what? So that the opposing enemy could save their ammunition.This substance also raises another question as to why things should be made solely for chemical weapons and have no other use? Of course the countering argument would be that there has been good to come from the making of mustard gas (i.e. fighting cancer).

I believe that it is necessary for chemical weapons to be developed, not only chemical weapons but it is necessary for all technology to develop. Only 1% of the medical cases having to do with mustard gas were fatal and those were only due to extremely prolonged exposure. Mustard gas was only very effective during World War 1, nowadays there is enough technology available so that mustard gas can be used without the adverse effects. Modern technology also allows for quick decontamination if anyone should come into contact with mustard gas. They would decontaminate someone by simplyto use peroxy acids (RCOOH, where R=C7H15, C9H19, C11H23, C13H27 ), as they react within a few seconds, and the reactions rate can be catalyzed. My final point would be that people need to realize that war is inevitable with the world having so many different cultures, religions, traditions, etc. and since war is inevitable those who go to war need to be more prepared than the enemy (technology wise). Many great bits of technology have surfaced from war efforts and they continue to benefit the civilian sector/ society tody.

A Brief History of Methanol

The earliest record of the use of methanol is when the early Egyptians used a mixture of substances, one of which was methanol, in their embalming process. The got the methanol from the chemical decomposition of wood. HOWEVER the first isolated use of the substance was in 1661 by Robert Boyle. In the 1970's because of the gas shortages people started to look for new/ alternative fuels. Methanol was accessible and affordable so mixtures of Methanol and Petrol were quite common. Recently, in 2006, astronomers discovered a 300 billion mile wide cloud of methanol in space.

Methanol as a Fuel

Methanol burns at a lower temperature than gasoline and is less volatile. One of the major concerns with the mixture of methanol and gasoline is the fact that being hygroscopic it absorbs water directly from the atmosphere. this would be a problem becuase the extra moisture would inevitably separate the mixture of petrol and methanol therefore making the mixture obsolete. So the mixture must be sealed completely for it to be successfully used. The going rate for Methanol is 47 cents per gallon.

There were not any videos on methanol that i could find, but here are a few about ethanol (which is very closely related). PLEASE REMEMBER that these videos are payed for by major corn producers and are in many ways bias...

Here is another interesting video that has not so much to do with ethanol/methanol but does have interesting information about biomass and waste turning into fuel.

Where is Methanol Found in Nature?

Wood (obviously) and Mint! Yes that's right Mint! Its extracted through steam distillation; The best type of Mint to get Methanol from is Corn Mint ( see below)

Uses of Methane

There are two major uses of methane are as fuel and industrial uses. Methane can be converted into the form of compressed natural gas and can be then used as a vehicle fuel. It can also be used to heat homes by steam boiler or gas turbine. This is said to be a more environmentally friendly fuel as it created or outputs less carbon dioxide than other hydro carbons such as petrol. NASA is currently trying to utilize methane's high flammability and use it somehow as rocket fuel!

History/Methane in Nature

  • Methane is found in nature mainly in natural gas fields, organic fermentation and also found in solid landfills
  • Comes from cow and sheep belches and excrement
  • As the permafrost in the northern tundra melts (due to global warming) this also releases a good amount of methane gas

Methane as a greenhouse gas

Methane is the number 2 greenhouse gas ( second only to water vapor) and has a net lifetime of approximately 8.4 years sustained in the atmosphere. The amount of methane in our atmosphere has increased by 150% since 1750. Methane is found naturally in wetlands, oceans and hydrates. However, this sharp increase is mainly do to the increase of anthropogenic emissions such as landfills, livestock, waste treatment and biomass burning. So in essence the increase of methane is do to the increased demand of the human population.

  • 23 times more harmful than carbon dioxide
  • 3rd largest contributor to global warming

A way that methane gas could help the world: instead of harm the earth. This video shows how as China is the leading country in coal usage and how coal distillation can give out methane gas AND how they plant to use this gas in an environmentally friendly way.

Here's another documentary in which methane gas is cited as a main cause in global warming:
