Industry:Chemistry
In an organic molecular structure, the occurrence when a pair of valence bonds that join a pair of carbons (or other atoms) shifts, via chemical reaction, to a new position, for example, H<sub>2</sub>C_C_C_CH<sub>2</sub> (butene-1) to H<sub>2</sub>C_C_C_CH<sub>2</sub> (butene-2).
Industry:Chemistry
C<sub>4</sub>H<sub>11</sub>NO<sub>8</sub>P<sub>2</sub> A white solid with a melting point of 203_C; quite soluble in water; used as a growth regulator in sugarcane.
Industry:Chemistry
Pb(C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>)<sub>2</sub>_3H<sub>2</sub>O Poisonous, water-soluble white crystals decomposing at 280_C; loses water at 75_C; used in hair dyes, medicines, and textile mordants, for waterproofing, for manufacture of varnishes and pigments, and as an analytical reagent. Also known as sugar of lead.
Industry:Chemistry
C<sub>14</sub>H<sub>18</sub>N<sub>2</sub>O<sub>5</sub> White to yellow crystals with sweet musk aroma; soluble in various oils and phthalates, insoluble in water; used as a perfume fixative. Also known as 3,5-dinitro-2,6-dimethyl-4-tert-butylacetophenone.
Industry:Chemistry
C<sub>15</sub>H<sub>21</sub>O<sub>2</sub>N<sub>3</sub> An alkaloid; poisonous, colorless-to-pinkish crystals; soluble in alcohol and dilute acids; melts at 86_C; used as a source of salicylate and sulfate forms. Also known as calabarine; eserine.
Industry:Chemistry
A brown, hygroscopic powder containing 7.5–8.5% silver; made by reaction of a silver compound with gelatin in the presence of an alkali; used as an antibacterial.
Industry:Chemistry
A salt which contains the CH<sub>3</sub>COCH<sub>2</sub>COO radical; derived from acetoacetic acid.
Industry:Chemistry
A member of the class of hydrocarbons, of which benzene is the first member, consisting of assemblages of cyclic conjugated carbon atoms and characterized by large resonance energies. Also known as arene.
Industry:Chemistry
A compound composed of only carbon and hydrogen atoms that contains three or more rings arranged topologically so as to enclose a volume of space; in general, the space within a cage hydrocarbon is too small to accommodate even a proton.
