p-디브로모벤젠 C화학적 특성, 용도, 생산
화학적 성질
1,4-dibromobenzene is a dibromobenzene. It is a white or off-white powder. freely soluble in hot ethanol, acetone, ether and hot benzene, soluble in ethanol and benzene, insoluble in water. It has a strong smell similar to that of the lighter chlorine analogue. It can be used as a precursor to the dye 6,6-Dibromoindigo.용도
1,4-Dibromobenzene is used in the synthesis of 2,5-dibromoacetophenone, triarylamines and trans- stilbenes. It is widely used as a heavy liquid solvent as well as a motor oil additive. It finds application as an intermediate in the manufacture of organic chemicals such as dyes, pharmaceuticals and flame retardants for polymeric materials.잠재적 노출
Dibromobenzene is used as a solvent for oils and in organic synthesis.운송 방법
UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required. UN2514 Bromobenzene, Hazard Class: 3; Labels: 3-Flammable liquid.Purification Methods
Steam distil the dibromobenzene , then crystallise it from EtOH or MeOH and dry it in the dark under vacuum. Purify it by zone melting. [Beilstein 5 IV 683.]비 호환성
Extremely flammable. May form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides.폐기물 처리
