Methyl alcohol, flash-point

Liquid stored methyl alcohol (flash point = 52°F)... 

Tetrahydronaphthalene [119-64-2] (Tetralin) is a water-white Hquid that is insoluble in water, slightly soluble in methyl alcohol, and completely soluble in other monohydric alcohols, ethyl ether, and most other organic solvents. It is a powerhil solvent for oils, resins, waxes, mbber, asphalt, and aromatic hydrocarbons, eg, naphthalene and anthracene. Its high flash point and low vapor pressure make it usehil in the manufacture of paints, lacquers, and varnishes for cleaning printing ink from rollers and type in the manufacture of shoe creams and floor waxes as a solvent in the textile industry and for the removal of naphthalene deposits in gas-distribution systems (25). The commercial product typically has a tetrahydronaphthalene content of >97 wt%, with some decahydronaphthalene and naphthalene as the principal impurities. 

Nature produces a tremendous amount of methyl aleohol, simply by the fermentation of wood, grass, and other materials made to some degree of eellulose. In faet, methyl aleohol is known as wood aleohol, along with names sueh as wood spirits and methanol (its proper name the proper names of all aleohols end in -ol). Methyl aleohol is a eolorless liquid with a eharaeteristie aleohol odor. It has a flash point of 54°F, and is highly toxie. It has too many eommereial uses to list here, but among them are as a denaturant for ethyl alcohol (the addition of the toxie ehemieal methyl aleohol to ethyl aleohol in order to form denatured aleohol), antifreezes, gasoline additives, and solvents. No further substitution of hydroxyl radieals is performed on methyl aleohol. 

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 ethyl ketone (MEK boiling point 769.6°C, density 0.8062, flash point -6°C) is an important coating solvent for many polymers and is made by the sulfation and hydration of 1 or 2-butene to sec-butyl alcohol, which is then dehydrogenated to the ketone (Fig. 1). 

DIACETONALKOHOL (German) or DIACETONE ALCOHOL or DIACETONE, 4-HYDROXY-4-METHYL-2-PENTATONE, 2-METHYL-2-PENTANOL-4-ONE (123-42-2) CgHijOj (CH3)jC(OH)CHjCOCH3 Forms explosive mixture with air [explosion limits in air (vol %) 1.8 to 6.9 flash point 125°F/51°C - 136°F/58°C the...
