Faʻapitoa i le gaosiga o le propargyl alcohol, 1,4 butynediol ma le 3-chloropropyne
1, 4-butanediol meatotino
Fa'aletino ma kemisi
Sua suau'u e leai ni lanu, mu, solu ile vai, methanol, ethanol, acetone, polyether ma
polyester polyols, soluble teisi i le eter, immiscible ma aliphatic ma manogi hydrocarbons.
O le mama o oloa gaosi oloa e masani ona sili atu nai lo le 99% poʻo le 99.5%, o le susu e itiiti ifo i le 0.1%, o le sulfur e le sili atu i le 0.1%, o le chroma (APHA) e itiiti ifo i le 25.
E sili atu i le 20 auala gaosiga o le 1, 4-butanediol, ae naʻo le 5 ~ 6 o loʻo faʻatauina moni.I le taimi nei, o auala autu alamanuia e aofia ai suiga Reppe metotia, maleic anhydride hydrogenation auala, maleic anhydride esterification hydrogenation auala, propylene oxide auala ma butadiene auala.
Uiga ma Fa'aoga
1, 4-butanediol o se vailaʻau faʻapitoa ma vailaʻau lelei, faʻaaogaina lautele i le gaosiga o palasitika ma filo faʻainisinia PBT, Faʻasologa o le tetrahydrofuran (THF), polytetramethylene ether diol (PTMEG, maua mai le THF polymerization), polyether high performance elastomer ma spandex elastic fiber (PTMEG ma diisocyanate synthesis), unsaturated polyester resin, polyester polyol, butanediol ether solvent, faʻapea foʻi ma falemaʻi ma mea teuteu.1, 4-butanediol e mafai foi ona faʻaaogaina e gaosia ai le N-methylpyrrolidone, adipic acid, acetal, maleic anhydride, 1, 3-butadiene ma isi.
Y-butanolactone, o le pito i lalo o le 1, 4-butanediol, o le mea mataʻutia mo le gaosiga o oloa 2-pyrrolidone ma N-methylpyrrolidone.Mai lenei mea, o loʻo maua mai ai se faʻasologa o oloa faʻaopoopo maualuga e pei o le vinyl pyrrolidone ma le polyvinyl pyrrolidone, lea e masani ona faʻaaogaina i vaega o vailaau faʻasaina, vailaʻau ma mea teuteu.
I le fanua o POLYURETHANE, i le faaopoopo atu i le tuufaatasia o polytetrahydrofuran polyol, e masani ona faaaoga i le tuufaatasia o le polyester diol ma faaaoga e pei o elastomer, microporous polyurethane seevae filifili extender, polybutanediol adipate ester polyurethane ua crystallization lelei.
Le oona oOona maualalo, taua tele oona o le gutu LD50= 1500-1780mg/kg i isumu, transdermal absorption oona taua ole lapiti LD50>2000mg/kg.
