1, 4-butanediol zog

1, 4-butanediol yog ib qho yooj yim tshuaj thiab zoo tshuaj raw khoom, dav siv nyob rau hauv zus tau tej cov PBT engineering yas thiab fibers, Synthesis ntawm tetrahydrofuran (THF), polytetramethylene ether diol (PTMEG, tau los ntawm THF polymerization), polyether siab elastomer thiab spandex elastic fiber (PTMEG thiab diisocyanate synthesis), unsaturated polyester resin, polyester polyol, butanediol ether hnyav, nrog rau kev lag luam tshuaj thiab tshuaj pleev ib ce.1, 4-butanediol tuaj yeem siv los tsim N-methylpyrrolidone, adipic acid, acetal, maleic anhydride, 1, 3-butadiene thiab lwm yam.

Y-butanolactone, cov khoom qis qis ntawm 1, 4-butanediol, yog cov khoom siv raw rau kev tsim cov khoom 2-pyrrolidone thiab N-methylpyrrolidone.Los ntawm qhov no, cov khoom lag luam muaj txiaj ntsig zoo ntxiv xws li vinyl pyrrolidone thiab polyvinyl pyrrolidone tau muab los, uas tau siv dav hauv cov tshuaj tua kab, tshuaj thiab tshuaj pleev ib ce.

Nyob rau hauv lub tshav pob ntawm POLYURETHANE, ntxiv rau cov synthesis ntawm polytetrahydrofuran polyol, feem ntau yog siv nyob rau hauv lub synthesis ntawm polyester diol thiab siv raws li elastomer, microporous polyurethane khau chain extender, polybutanediol adipate ester polyurethane muaj crystallization zoo.

toxicity ntawmTsawg toxicity, mob toxicity tus nqi ntawm qhov ncauj LD50 = 1500-1780mg / kg hauv nas, transdermal absorption toxicity tus nqi ntawm luav LD50> 2000mg / kg.
