110-52-1 - Daim Ntawv Thov:

1,4-Dibromobutane (CAS: 110-52-1) yog siv los ua ib qho nruab nrab koom nrog hauv kev sib txuas ntawm cov khoom siv tshuaj nquag thiab lwm cov tshuaj organic.Organic synthesis intermediates.1,4-Dibromobutane yog siv rau kev tsim cov aminophylline, kebiqing, tshem tawm Qingjing, thiab lwm yam. 1,4-Dibromobutane yog siv los ua cov catalyst hauv polymerization ntawm 2-oxazolines.Kuj tseem siv rau hauv kev sib txuas ntawm cholinesterase inhibitors siv tawm tsam Alzheimer's kab mob.

110-52-1 - Txheej Txheem:

1. 1,4-Dibromobutane yog muab los ntawm tetrahydrofuran los ntawm lub nplhaib qhib thiab bromination.Hydrobromic acid tau ntxiv rau cov tshuaj tiv thaiv Pan, tetrahydrofuran tau ntxiv dropwise nyob rau hauv nplawm, thiab sulfuric acid tau ntxiv dropwise, thiab kub tau tswj kom qis dua 50 ℃.Tom qab ua tiav cov tshuaj tiv thaiv, qhov sib tov yog stirred rau 1H.Cov tshuaj qis dua tau muab cais los ntawm qhov txias, ntxuav nrog dej qab zib tshauv kom txog thaum nruab nrab, qhuav nrog anhydrous calcium chloride, thiab lim kom tau cov khoom tiav.

2. Muab los ntawm bromination ntawm 1,4-Butanediol.Hydrobromic acid tau ntxiv rau cov tshuaj tiv thaiv lub lauj kaub, txias rau 10 ℃ nrog nplawm, thiab sulfuric acid ntxiv dropwise.Tom qab ua tiav ntawm qhov sib ntxiv, 1,4-Butanediol tau ntxiv dropwise ntawm qhov kub tsis tshaj 15 ℃, thiab qhov sib tov tau nplawm rau ib nrab ib teev.Incubation tau ua rau 6h ntawm 100-110 ℃.Txias rau hauv chav tsev kub, cais cov kua qis, ntxuav nrog dej qab zib tshauv tov rau nruab nrab.Tom qab lub cev qhuav dej ntawm calcium chloride, 1,4-Dibromobutane tau txais los ntawm kev pom.

110-52-1 - Kev Cia thiab Kev Thauj Mus Los:

Khaws rau hauv qhov chaw txias thiab qhov cua, kom deb ntawm qhov hluav taws kub.Khaws lub thawv ntim thiab khaws cia kom deb ntawm cov oxidant.Cov khoom siv thaum muaj xwm txheej ceev thiab cov khoom ntim khoom tsim nyog yuav tsum tau muab.
