디비닐벤젠 C화학적 특성, 용도, 생산
화학적 성질
A water-white to straw colored liquid. Slightly less dense than water and insoluble in water. Flash point below 141°F. Vapors may be toxic. Used in making rubber.용도
Divinylbenzene is a specialty monomer used primarily to make cross-linked polystyrene resins. The largest use of divinylbenzene (DVB) [CAS: 1321-74-0] is in ion-exchange resins for domestic and industrial water softening. Ion-exchange resins are also used as solid acid catalysts for certain reactions, such as esterification. Divinylbenzene is manufactured by dehydrogenation of diethylbenzene, which is an internal product in the alkylation plant for ethylbenzene production.일반 설명
Divinylbenzene (DVB) consists of a combination of meta and para isomers of DVB and ethylvinylbenzene. It can be used as a monomer for the preparation of linear polydivinylbenzene by anionic polymerization.공기와 물의 반응
Flammable. Insoluble in water.반응 프로필
Divinylbenzene may react vigorously with strong oxidizing agents. Can react exothermically with reducing agents (such as alkali metals and hydrides) to release gaseous hydrogen. May react exothermically with both acids and bases. May in the presence of various catalysts (such as acids) or initiators undergo exothermic polymerization. Inhibited by presence of an additive. When uninhibited violent polymerization may occur . Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.건강위험
Divinyl benzene is an irritant of eyes, nose, and mucous membranes.Mild respiratory irritation occurred in workers exposed to 0.4–4ppm divinyl benzene. Mild irritation was also reported from skin and eye contact.
화재위험
Divinylbenzene is combustible.Safety Profile
Mildly toxic by ingestion. An eye irritant. Combustible. When heated to decomposition it emits acrid smoke and irritating fumes.Carcinogenicity
Divinyl benzene was weakly genotoxic in vivo, inducing a dose-dependent increase in sister chromatid exchanges and an increase in the frequency of chromosome aberrations in male mice exposed at concentrations of up to 75ppm for 3 days.The 2003 ACGIH threshold limit valuetime- weighted average (TLV-TWA) for divinyl benzene is 10ppm (53mg/m3).
Purification Methods
Purify divinylbenzene by dissolving in Et2O, shaking with H2O, drying over CaCl2, filtering, evaporating and distilling in vacuo. It polymerises within 2-3days unless 4-tertbutylcatechol (0.05%) is added as stabilizer. [Fries & Bestian Chem Ber 69 715 1936, Beilstein 5 III 1366.]디비닐벤젠 준비 용품 및 원자재
