Intangiriro
Trans-4-bromo-2-butenoic aside methyl ester ni amazi atagira ibara afite impumuro idasanzwe. Ifite ubucucike bwa 1.49g / cm3, ahantu hatetse nka 171-172 ° C, no kumurika nka 67 ° C. Ntishobora gushonga mumazi mubushyuhe bwicyumba, ariko ntishobora gukoreshwa numuti ukomoka kuri organic nka Ethanol, ether, nibindi.
Koresha:
Trans-4-bromo-2-butenoic aside methyl ester ikoreshwa cyane cyane hagati yigihe cyo guhuza ibinyabuzima. Irashobora gukoreshwa muguhuza ibindi bintu kama kama, kurugero rwo guhuza ibice muri chimie miti na chimie pesticide.
Uburyo bwo Gutegura:
Trans-4-bromo-2-butenoic aside methyl ester isanzwe itegurwa na bromination reaction na esterification reaction. Butene yabanje gukoreshwa na bromine kugirango itange 4-bromo-2-butene, hanyuma igashyirwa hamwe na methanol kugirango itange trans-4-bromo-2-butenoic aside methyl ester.
Amakuru yumutekano:
Trans-4-bromo-2-butenoic aside methyl ester ni ubwoko bwimiti kama nibikoresho fatizo bya chimique, bifite akaga runaka. Birakaze kandi byangirika, kandi guhura nuruhu, amaso cyangwa inzira zubuhumekero birashobora gutera uburakari no gukomeretsa. Guhuza bitaziguye bigomba kwirindwa mugihe cyo kubikoresha, kandi hagomba gufatwa ingamba zo gukingira no guhumeka neza. Byongeye kandi, hakwiye kwitonderwa kugirango wirinde guhura na okiside na acide zikomeye mugihe cyo kubika kugirango wirinde ingaruka mbi. Niba ukeneye gukoresha uru ruganda, nyamuneka ukorere ahantu hizewe kandi ukurikize inzira zakazi zifite umutekano.
