Nyanzvi mukugadzira propargyl doro, 1,4 butynediol uye 3-chloropropyne.
1, 4-butanediol zvinhu
Zvenyama uye zvemakemikari zvinhu
Mvura isina ruvara ine mafuta, inobvira, inonyungudika mumvura, methanol, ethanol, acetone, polyether uye
polyester polyols, inonyungudika zvishoma muether, isingaenderani nealiphatic uye anonhuwirira hydrocarbons.
Kuchena kwezvigadzirwa zvemaindasitiri kazhinji kwakakura kupfuura 99% kana 99.5%, hunyoro huri pasi pe0.1%, kukosha kwesarufa hakusi kudarika 0.1%, chroma (APHA) isingasviki makumi maviri neshanu.
Kune anopfuura makumi maviri nzira dzekugadzira dze 1, 4-butanediol, asi chete 5 ~ 6 ndiwo chaiwo maindasitiri.Parizvino, nzira huru dzemaindasitiri dzinosanganisira yakagadziridzwa Reppe nzira, maleic anhydride hydrogenation nzira, maleic anhydride esterification hydrogenation nzira, propylene oxide nzira uye butadiene nzira.
Hunhu uye Mashandisirwo
1, 4-butanediol ikemikari yakakosha uye yakanaka makemikari mbishi zvinhu, inoshandiswa zvakanyanya mukugadzirwa kwePBT engineering mapurasitiki nemafiber, Synthesis ye tetrahydrofuran (THF), polytetramethylene ether diol (PTMEG, inowanikwa neTHF polymerization), polyether high performance elastomer. uye spandex elastic fiber (PTMEG uye diisocyanate synthesis), unsaturated polyester resin, polyester polyol, butanediol ether solvent, pamwe chete neindasitiri yemishonga uye cosmetic.1, 4-butanediol inogonawo kushandiswa kugadzira N-methylpyrrolidone, adipic acid, acetal, maleic anhydride, 1, 3-butadiene nezvimwe zvakadaro.
Y-butanolactone, iyo yakadzika chigadzirwa che1, 4-butanediol, ndiyo inoshandiswa pakugadzirwa kwe2-pyrrolidone uye N-methylpyrrolidone zvigadzirwa.Kubva pane izvi, mutsara wezvigadzirwa zvepamusoro zvakakosha zvakadai sevinyl pyrrolidone uye polyvinyl pyrrolidone inotorwa, iyo inoshandiswa zvakanyanya muminda yemishonga yemishonga, mishonga uye cosmetics.
Mumunda wePOLYURETHANE, kuwedzera kune kuumbwa kwe polytetrahydrofuran polyol, inonyanya kushandiswa mukugadzirwa kwepolyester diol uye inoshandiswa se elastomer, microporous polyurethane shangu chain extender, polybutanediol adipate ester polyurethane ine yakanaka crystallization.
Muchetura weLow toxicity, acute toxicity kukosha kwemuromo LD50 = 1500-1780mg / kg mumakonzo, transdermal absorption toxicity kukosha kwetsuro LD50> 2000mg/kg.
