Chemical manufacturing, chemicals used methyl alcohol

However, if you link the hydroxyl group with the methane molecule rather than the ethane, you get the potentially toxic chemical called methyl alcohol, or wood spirit. Similarly, if you add what s called an aldehyde group (-CHO) instead of the hydroxyl group, you will get one of a variety of chemicals called aldehydes, of which a common one is the gas formaldehyde (HCHO), widely used in the manufacture of plastics and glues. This gas can be an irritant and potentially dangerous if inhaled. 

Uses Manufacture of vanillin, Michler s ketone, methyl violet, and other dyes solvent reagent for methyl alcohol, hydrogen peroxide, methyl furfural, nitrate, and formaldehyde chemical intermediate stabilizer reagent. 

Use Blast furnaces copper smelting steel production (basic oxygen converter process) manufacture of synthesis gas for production of ammonia, methyl alcohol, acetylene, etc. oxidizer for liquid rocket propellants resuscitation, heart stimulant decompression chambers spacecraft chemical intermediate to replace air in oxidation of municipal and industrial organic wastes to counteract effect of eutrophication in lakes and reservoirs coal gasification. 

In Japan, Mitsui, Petrochemical and Kuraray Isoprene Chemical manufacture 52,000 and 13,000 t/year of tertiary butyl alcohol respectively used for ihe manufacture of methyl methacrylate, employing the reverse operation to the above, namely the hydration of isobutene. 

Ihe crude product ia su ected to a first purification by distillation the first portions are collected separately and yield methyl alcohol (q. v.) the remainder of the distillate is the disdUed pyrolupieouB odd, used to a limited extent as an antiseptic, but prindp y for the manufacture of acetic add and the acetates It can only be freed from the impurities which it still contains by chemical means to this end slacked lime and chalk are added, at a gentle heat, to neutralization the liquid is boiled and allowed to settle twenty-four hours the clear liquid, which is a solution of calcium acetate, is decanted and evaporated the caldum salt is converted into sodium acetate, which is then purified by calcination at a temperatxire below 330° (626° F.), dissolved, filtered, and recrystallized the salt is then decomposed by a proper quantity of H,SO, and the Ixber-ated tic acid separated by distillation. 

A second very important use of petroleum is in the manufacture of plastics and other chemicals. The number of chemical compounds obtained from petroleum and used as raw materials in chemical reactions is almost endless. It includes compounds such as methane, ethane, propane, butane, ethene (ethylene), propene (propylene), butene (butylene), benzene, methanol (methyl alcohol), ethanol (ethyl alcohol), phenol, xylene, naphthalene, and anthracene, to mention only a few. 

The poisonous methyl alcohol was (and still is) used by governments to denature ethyl alcohol, in order to allow manufacture and sale of the latter for chemical purposes without beverage taxes. 

Diethylethanolamine (Diethylaminoethanol, (CtHOrNCrHrOH). Di-ethylaminoethanol is a water-white, hygroscopic liquid which behaves chemically like the tertiary amines and alcohols. It is soluble in water, ethyl alcohol, methyl alcohol, ethyl ether, ethyl acetate, acetone, aromatic hydrocarbons, fixed oils, mineral oil, oleic acid, hot stearic acid, and hot paraffin and carnauba wa.xes, the last two solidifying when cooled. It is used in the manufacture of certain pharmaceuticals, such as procaine and "atabrine". It forms amine soaps with higher fatty acids, which are oil-soluble and useful as emulsifiers and textile lubricants. Its mild alkalinity makes it applicable as a neutralizing agent and a corrosion inhibitor. 

The U.S. and European production figures for acetone are approximately M and 0-5 Mt per annum respectively. The largest single chemical use (approx. 30%) is in methyl methacrylate manufacture. Of the aldol derivatives, methyl isobutyl ketone (MIBK) (4-methylpentan-2-one) takes some 10-15%, but several others, such as diacetone alcohol and isophorone, have individual sales of 10 to 25 kt per annum (for brake fluids, speciality solvents, etc.). 

Hydrogen is used to manufacture a number of chemicals. One of the most important of these is ammonia, NH3. Methanol (methyl alcohol), CH3OH, is a widely used industrial chemical and solvent synthesized by the following reaction between carbon monoxide and hydrogen ... 

Methanol, also known as methyl alcohol or wood alcohol, is used as a chemical building block in the manufacture of wood paneling, paints, adhesives, and fuels. It is poisonous when consumed by humans. 

In addition to water solutions, other liquid chemicals can be the basis for solution formation and use. Examples include crude oil (the source of organic chemicals), manufactured oils, many petroleum distillates, and nonwater solvents used for cleaning. Gasoline, kerosene, and other fuels are solutions. In addition, organic solvents, such as acetone and methyl alcohol, are used as solvents in industrial laboratories. It follows that students of chemistry should devote much attention to this state of matter known as a solution. 

Or suppose that after graduation you go to work for a chemical company that makes methanol (methyl alcohol), a substance used as a starting material for the manufacture of products such as antifreeze and aviation fuels and as a fuel in the cars that race in the Indianapolis 500 (see Chemistry in Focus on p. 257. You are working with an...
