Kaihanga Utu Pai Tetrahydrofuran CAS:109-99-9

whakaahuatanga poto:

Ko te Tetrahydrofuran (THF) he wai karekau he tae, he wai whakakorikori me te haunga ethereal, acetonelike ranei, a ka hee ki roto i te wai me te nuinga o nga whakarewa pararopi. Ko te Tetrahydrofuran (THF) he tino muramura ka taea te waiariki te pirau ki te waro monoxide me te waro waikura.Ko te roa o te rokiroki ka pa ki te hau me te kore he antioxidant ka pirau pea te THF ki nga peroxide pahū.

Nga tono a Tetrahydrofuran

Ka whakamahia te Tetrahydrofuran ki te hanga polymers tae atu ki nga matū ahuwhenua, rongoa, me nga taonga.Ko nga mahi whakangao ka mahia i roto i nga punaha kati, i raro ranei i nga mana miihini e whakatiki ana i te tukunga o nga kaimahi ki te taiao.Ka whakamahia ano te THF hei whakarewa (hei tauira, he paipa paipa) ka nui ake nga whakaaturanga ina whakamahia ki nga waahi kati karekau he hau.Ahakoa kei roto te THF i roto i te kakara kawhe, i te pipi paraoa, me te heihei maoa, karekau e whakaaro ka puta he moreareatanga nui.
Ko te Butylene oxide ka whakamahia hei whakangao me te kore whakauru ki etahi atu puhui.Ka whakamahia hei whakapumau i te wahie e pa ana ki te tae me te hanga para.
Ka whakamahia te Tetrahydrofuran hei whakarewa mo te reini, vinyls, me te polymers teitei;hei reo Grignardreaction mo nga tauhohenga organometallic, me te whakarewa hydride;me te whakahiatotanga o te waikawa succinic me te butyrolactone.
Te whakarewa mo nga polymers teitei, ina koa te polyvinyl chloride.Hei reo tauhohenga mo Grignard me nga tauhohenga hydride whakarewa.I roto i te whakahiato o butyrolactone, waikawa succinic, 1,4-butanediol diacetate.Te whakarewa i roto i nga tikanga histological.Ka taea te whakamahi i raro i te Federal Food, Drug & Cosmetic Act mo te hanga tuhinga mo te takai, te kawe, te penapena kai ranei ki te kore e nui ake te toenga o te 1.5% o te kiriata: Fed.Rēhita.27, 3919 (Aperira 25, 1962).
Ka whakamahia te Tetrahydrofuran (80%) ki te hanga polytetramethylene ether glycol, te polymer turanga i whakamahia tuatahi ki te hanga i nga muka elastomeric (hei tauira, spandex) tae atu ki te polyurethane me te polyester elastomers (hei tauira, hiako horihori, wira papareti).Ko te toenga (20%) ka whakamahia i roto i nga tono whakarewa (hei tauira, nga raima paipa, te whakapiri, te waituhi ta, me te rīpene autō) me te whakarewa tauhohenga i roto i te whakahiato matū me te rongoa.
