Nā huahana
Hana kūikawā i ka hana ʻana i ka waiʻona propargyl, 1,4 butynediol a me 3-chloropropyne
1, 4-butanediol waiwai
ʻAno kino a me kemika
ʻO ka wai aila kala ʻole, hiki ke puhi ʻia, hiki ke hoʻoheheʻe ʻia i ka wai, methanol, ethanol, acetone, polyether a me
polyester polyols, hoʻoheheʻe iki i ka etera, immiscible me aliphatic a me ka aromatic hydrocarbons.
ʻOi aku ka maʻemaʻe o nā huahana ʻoihana ma mua o 99% a i ʻole 99.5%, ʻoi aku ka maʻemaʻe ma mua o 0.1%, ʻoi aku ka nui o ka sulfur ma mua o 0.1%, ʻo ka chroma (APHA) ka liʻiliʻi ma mua o 25.
ʻOi aku ma mua o 20 mau hana hana o 1, 4-butanediol, akā ʻo 5 ~ 6 wale nō i hana ʻia.I kēia manawa, ʻo nā ʻano hana ʻenehana nui i hoʻololi ʻia ke ʻano Reppe, maleic anhydride hydrogenation method, maleic anhydride esterification hydrogenation method, propylene oxide method and butadiene method.
Nā ʻano a me nā mea hoʻohana
ʻO 1, 4-butanediol kahi mea kemika maʻamau a me nā mea kemika maikaʻi, hoʻohana nui ʻia i ka hana ʻana i nā plastic engineering PBT a me nā fibers, Synthesis of tetrahydrofuran (THF), polytetramethylene ether diol (PTMEG, loaʻa e THF polymerization), polyether high performance elastomer a me ka spandex elastic fiber (PTMEG a me diisocyanate synthesis), unsaturated polyester resin, polyester polyol, butanediol ether solvent, a me ka ʻoihana lāʻau lapaʻau a me nā mea hoʻonaninani.Hiki ke hoʻohana ʻia ka 1, 4-butanediol e hana i ka N-methylpyrrolidone, adipic acid, acetal, maleic anhydride, 1, 3-butadiene a pēlā aku.
ʻO Y-butanolactone, ka huahana lalo o 1, 4-butanediol, ka mea maka no ka hana ʻana i nā huahana 2-pyrrolidone a me N-methylpyrrolidone.Mai kēia, ua loaʻa kahi pūʻulu o nā huahana waiwai nui e like me vinyl pyrrolidone a me polyvinyl pyrrolidone, i hoʻohana nui ʻia i nā ʻano pesticides, lāʻau lapaʻau a me nā mea hoʻonaninani.
Ma ke kahua o POLYURETHANE, i ka hoʻohui i ka synthesis o polytetrahydrofuran polyol, nui i hoʻohana 'ia i loko o ka synthesis o polyester diol a hoʻohana 'ia e like me elastomer, microporous polyurethane kāmaʻa kaulahao extender, polybutanediol adipate ester polyurethane he maikai crystallization.
ʻO ka ʻona oʻO ka ʻawaʻawa haʻahaʻa, ka waiwai ʻawaʻawa nui o ka waha LD50= 1500-1780mg /kg i nā ʻiole, ka waiwai ʻawaʻawa transdermal absorption o ka lākeke LD50>2000mg/kg.
