Methyl alcohol Methanol

Methyl alcohol (methanol) is the first member of the aliphatic alcohol family. It ranks among the top twenty organic chemicals consumed in the U.S. The current world demand for methanol is approximately 25.5 million tons/year (1998) and is expected to reach 30 million tons by the year 2002. The 1994 U.S. production was 10.8 billion pounds.

On the other hand, drugs may inhibit the metabolism of other drugs. For example, allopurinol (a xanthine oxidase inhibitor that inhibits the synthesis of uric acid) increases the effectiveness of anticoagulants by inhibiting their metabolism. Chloramphenicol (a potent inhibitor of microsomal protein synthesis) and cimetidine (an H2-receptor blocker used in acid-pepsin disease) have similar properties. In addition, drugs may compete with each other in metabolic reactions. In methyl alcohol (methanol) poisoning, ethyl alcohol may be given intravenously to avert methanol-induced blindness and minimize the severe acidosis. Ethyl alcohol competes with methyl alcohol for... 

Methyl alcohol (methanol wood alcohol) a colorless, volatile, inflammable, and poisonous alcohol (CH,OH) traditionally formed by destructive distillation (q.v.) of wood or, more recently, as a result of synthetic distillation in chemical plants.

Methyl alcohol (methanol, wood alcohol, CH3OH boiling point 64.7°C, density 0.7866, flash point 110°C) is a colorless, mobile liquid with a mild characteristic odor (and narcotic properties) that is miscible in all proportions with water, ethyl alcohol, or ether. When ignited, methyl alcohol burns in air with a pale blue, transparent flame, producing water and carbon dioxide. The vapor forms an explosive mixture with air. The upper explosive limit is 36.5% and the lower limit is 6.0% by volume in air. 

Methyl alcohol (methanol) is manufactured from a mixture of carbon monoxide and hydrogen (synthesis gas), using a copper-based catalyst.

Alcohols are some of the most common organic compounds. Methyl alcohol (methanol), also known as wood alcohol, is used as an industrial solvent and as an automotive racing fuel. Ethyl alcohol (ethanol) is sometimes called grain alcohol because it is produced by the fermentation of grain or almost any other organic material. Isopropyl alcohol is the common name for propan-2-ol, used as rubbing alcohol. ... 

A mixture consisting of phenyl isocyanate (0.3 mmol), the Step 5 product (0.3 mmol), and 1 ml CHC13 was stirred 48 hours at ambient temperature and concentrated. The residue was dissolved in 0.5 ml methyl alcohol methanol and purified as in Step 6 and the product isolated. 

Acetic acid (0.448 ml) was added to a solution of the Step 2 product (873 mg) and tryptamine (640 mg) dissolved in 40 ml THF containing 10 ml 1,2-dichloroethane and stirred 15 minutes. Sodium triacetoxyboron hydride (1.2 g) was introduced and the mixture stirred 3 days at ambient temperature and was then concentrated. The residue was dissolved in 40 ml apiece 1M NaOH solution and diethyl ether, while the aqueous phase was extracted twice with 30 ml diethyl ether. Combined extracts were then dried and concentrated. The residue was purified by chromatography using silica gel with methyl alcohol/(methanol/ammonia), 100 1, and 617 mg product isolated as a white solid, mp = 150-152°C. 

The current interest in alcohols as motor fuels is rooted in the search for alternate fuels to replace our suddenly limited petroleum-based fuels. The fact that methyl alcohol (methanol) can be produced from a variety of sources, including coal and garbage, has focused considerable attention on this material as a possible alternate fuel. The fact that the tech-...
