1,3-Butadiene / CAS 106-99-0

Imikoreshereze

Ikoreshwa nk'ibikoresho fatizo mu gukora rabu ya sintetike, resin ya sintetike, fibre ya sintetike, pulasitiki, irangi rya latex, nibindi. Butadiene ni yo bikoresho fatizo by'ingenzi mu gukora rabu ya sintetike (rubber ya styrene-butadiene, rubber ya cis-polybutadiene, rubber ya nitrile-butadiene, rubber ya chloroprene). Hamwe n'iterambere rya pulasitiki ya styrene, hakoreshejwe copolymerizing styrene na butadiene, hakorwa resin zitandukanye zifite akamaro kanini (nka resin ya ABS, resin ya SBS, resin ya BS, resin ya MBS), bituma butadiene ifata umwanya ukomeye mu gukora resin. Byongeye kandi, butadiene ikoreshwa kandi mu gukora ethylidene norbornene (monomeri ya gatatu ya ethylene-propylene rubber), 1,4-butanediol (plastiki yo gushushanya), adiponitrile (monomeri ya nylon 66), sulfolane, anthraquinone, tetrahydrofuran, nibindi. Kubwibyo, ni kandi ibikoresho fatizo by'ingenzi by'ubutabire. Butadiene ifite kandi akamaro kenshi mu gukora imiti myiza. Imiti myiza ikorwa hakoreshejwe butadiene nk'ibikoresho fatizo ahanini ikubiyemo ibi bikurikira: (1) Inyura mu buryo bwa Diels-Alder hamwe n'ibinyabutabire bya dieneophile bidafite electron kugira ngo ikore anthraquinone, kandi ibikomoka kuri yo ni ingenzi mu gutera irangi, imiti yica udukoko, n'imiti yica udukoko. (2) Ikorana na anhydride ya maleic (mu magambo ahinnye nka anhydride ya maleic) hanyuma igahinduka ingirabuzimafatizo kugira ngo ikore anhydride ya tetrahydrophthalic, ishobora gukoreshwa nk'ikintu gitanga umuti n'ibumba rya pulasitiki kuri resins za polyester na resins za epoxy. Iyo anhydride ya tetrahydrophthalic yongeye gukurwamo aside nitrique, aside ya butane tetracarboxylic irashobora kuboneka, ikaba ari igikoresho fatizo cyo gukora amarangi ashongera mu mazi. Mu buryo nk'ubwo, iyo anhydride ya tetrahydrophthalic ishyizwemo hydrogen kugira ngo ikore anhydride ya hexahydrophthalic, ishobora gukoreshwa nk'ikintu gitanga umuti kuri resins za epoxy. (3) Ikorana na dioxyde sulfur kugira ngo ikore sulfolene, hanyuma igakorwamo umuti w'amazi hanyuma igaterwa na hydrogen imbere y'agakoresho ka nikeli gashinzwe gukurura sulfolane, ikaba ari umuti utoranywa wo gukuramo hydrocarboni nziza. Uruvange rwa sulfolane na diisopropanolamine rushobora gukoreshwa mu gukuraho umwuka wa carbonide. (4) Uburyo butadiene ikora neza mu nganda. Nyuma yo gukuramo carbonide, haboneka olefine ifite umugozi umwe wa karuboni, hanyuma nyuma yo gukuramo hydrogenation na hydrogenation, haboneka nonanol, ifite akamaro kanini mu gukora impumuro nziza, surfactants, n'ibindi birungo. Hakoreshejwe cobalt complex nk'umuti, dimer, trimer, na tetramer byose ni ibikoresho fatizo byo gukora alcohols nyinshi na macrocyclic musks. Irashonga mu alcohols na ethers, kandi ishobora no gushonga muri acetone, benzene, dichloroethane, amyl acetate, furfural, na cuprammonium acetate. Ntishobora gushonga mu mazi.

Gupakira no Kohereza

nk'ibisabwa n'abakiriya.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere

Bika kandi ubibike

Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
