C<sub>7</sub>H<sub>6</sub>N<sub>2</sub> Colorless crystals; melting point 170_C; slightly soluble in water, soluble in ethanol; used in organic synthesis.
Industry:Chemistry
For addition (chain) polymerization, the temperature at which the propagation and depropagation rates are equal, that is, the net rate of polymer formation is zero. Above the ceiling temperture, depolymerization, an unzipping reaction to reform monomer, occurs.
Industry:Chemistry
CH<sub>3</sub>COCH<sub>2</sub>C(CH<sub>3</sub>)<sub>2</sub>OH A colorless liquid used as a solvent for nitrocellulose and resins.
Industry:Chemistry
A catalyst derived from reaction of an alkali alcoholate with an olefin halide; used to convert olefins (for example, ethylene, propylene, or butylenes) into polyolefin polymers.
Industry:Chemistry
C<sub>6</sub>H<sub>4</sub>SCHN A thiazole fused to a benzene ring; can be made by ring closure from o-amino thiophenols and acid chlorides; derivatives are important industrial products.
Industry:Chemistry
C<sub>7</sub>H<sub>8</sub>N<sub>2</sub>O<sub>2</sub> Monohydrate crystals with a melting point of 228_C; soluble in organic solvents such as alcohol and benzene; used in the detection and determination of nitrites.
Industry:Chemistry
The radical CH<sub>3</sub>CHNH<sub>2</sub>CO_; occurs in, for example, alanyl alanine, a dipeptide.
Industry:Chemistry
A salt or ester of benzoic acid, formed by replacing the acidic hydrogen of the carboxyl group with a metal or organic radical.
Industry:Chemistry
C<sub>12</sub>H<sub>22</sub>O<sub>11</sub> A disaccharide which does not occur freely in nature or as a glucoside; a unit of cellulose and lichenin; crystallizes as minute watersoluble crystals from alcohol. Also known as cellose.
