Ibicuruzwa
Inzobere mu gukora inzoga za propargyl, 1,4 butynediol na 3-chloropropyne
1, 4-butanediol
Imiterere yumubiri nubumara
Amazi adafite ibara ryamazi, yaka, ashonga mumazi, methanol, Ethanol, acetone, polyether na
polyester polyole, gushonga gato muri ether, idashobora gukoreshwa na hydrocarbone ya alifatique na aromatic.
Ubusanzwe ibicuruzwa biva mu nganda birenze 99% cyangwa 99.5%, ubuhehere buri munsi ya 0.1%, agaciro ka sulferi ntikurenga 0.1%, chroma (APHA) iri munsi ya 25.
Hariho uburyo burenga 20 bwo gukora bwa 1, 4-butanediol, ariko 5 ~ 6 gusa ni inganda.Kugeza ubu, uburyo nyamukuru bwateye imbere mu nganda burimo uburyo bwa Reppe bwahinduwe, uburyo bwa hydrogène ya hydrogène ya manic anhydride, uburyo bwa hydrogenation ya manic anhydride, uburyo bwa okiside ya propylene nuburyo bwa butadiene.
Ibiranga n'imikoreshereze
1. na spandex elastique fibre (PTMEG na synthesis ya diisocyanate), resin ya polyester idahagije, polyester polyol, butanediol ether solvent, hamwe ninganda zimiti no kwisiga.1, 4-butanediol irashobora kandi gukoreshwa mugukora N-methylpyrrolidone, aside adipic, acetal, anhydride yumugabo, 1, 3-butadiene nibindi.
Y-butanolactone, ibicuruzwa byo hasi ya 1, 4-butanediol, nibikoresho fatizo byo gukora ibicuruzwa 2-pyrrolidone na N-methylpyrrolidone.Duhereye kuri ibi, urukurikirane rw'ibicuruzwa byongerewe agaciro nka vinyl pyrrolidone na polyvinyl pyrrolidone bikomoka, bikoreshwa cyane mu bijyanye n'imiti yica udukoko, imiti n'amavuta yo kwisiga.
Mu rwego rwa POLYURETHANE, usibye synthesis ya polytetrahydrofuran polyol, ikoreshwa cyane muri synthesis ya polyester diol kandi ikoreshwa nka elastomer, microporous polyurethane inkweto zagutse, polybutanediol adipate ester polyurethane ifite kristu nziza.
Uburozi bwaUburozi buke, uburozi bukabije bwumunwa LD50 = 1500-1780mg / kg mu mbeba, uburozi bwimyanya ndangagitsina agaciro k'urukwavu LD50> 2000mg / kg.
