Te whakamahinga o te butanediol i roto i nga mea whakapaipai
Butanediol, te nuinga o te acetylene me te formaldehyde hei rauemi mata.Ka whakamahia hei kaiwhakawhanui mekameka mo te hanga o te polybutylene terephthalate me te polyurethane, me te mea he rauemi mata nui mo te tetrahydrofuran, γ-butyrolactone, rongoa me te whakahiato waro.Na te mea he momo polyester te polybutylene terephthalate me nga taonga pai, kei te tere haere te tono mo nga kirihou miihini.

He matū taiwhanga tino paitini - te waipiro propargyl
Propargyl Alcohol, tātai rāpoi C3H4O, taimaha rāpoi 56. He wai marama kore tae, he pahekeheke me te hongi, he paitini, he mate kino ki te kiri me nga kanohi.He takawaenga i roto i te whakahiato waro.Te nuinga whakamahia mō te kōtuitanga o antibacterial me anti-inflammatory drugs sulfadiazine;I muri i te hauwaitanga wahanga, ka taea e te waipiro propylene te whakaputa kapia, a, i muri i te hauwaitanga katoa, ka taea te whakamahi i te n-propanol hei rauemi mata o te ethambutol tarukino anti-mate kohi, me etahi atu hua matū me te rongoa.Ka taea te aukati i te waikawa ki te rino, te parahi me te nickel me etahi atu konganuku te waikura, whakamahia hei tango waikura.Ka whakamahia nuitia ki te tango hinu.Ka taea hoki te whakamahi hei whakarewa, hei whakapumau i te hauwai maataa, te patu patupatu me te ngarara.Ka taea te whakamahi mo te hanga waikawa kiriaku, acrolein, 2-aminopyrimidine, γ-picauline, huaora A, stabilizer, aukati waikura me etahi atu.
Ko etahi atu ingoa: te waipiro propargyl, 2-propargyl – 1-waipiro, 2-propargyl waipiro, propargyl alcohol acetylene methanol.

Ka polymerize a Propargyl ka pahū
Ko te tukanga tuatahi kei runga i te waipiro propargyl hei whakarewa, KOH hei turanga, te tauhohenga whakawera kia whiwhi ai i te whaainga.Ko te tauhohenga kaore he tikanga waimeha whakarewa ka iti ake te poke, he ma ake te tauhohenga.
I runga i te whakaaro ki te polymerization catalytic pea me te pirau pahū o nga alkynes kāpeka, i kuhu atu te Amgen's Hazard Evaluation Lab (HEL) ki te mahi i nga aromatawai haumaru me te awhina i te arotautanga o nga mahi i mua i te piki ake ki te 2 rita o te tauhohenga.
Ko te whakamatautau DSC e whakaatu ana ka timata te tauhohenga ki te pirau i te 100 °C me te tuku i te 3667 J/g pūngao, i te wa e hono tahi ai te waipiro propargyl me te KOH, ahakoa ka heke te kaha ki te 2433 J/g, engari ka heke ano te pāmahana pirau ki te 85 °C, a he tata rawa te pāmahana o te tukanga ki te 60 °C, he nui ake te noho haumaru.

1,4-butanediol (BDO) me tana whakaritenga o te PBAT kirihou koiora
1, 4-butanediol (BDO);Ko te PBAT he kirihou hauhautanga koiora, he copolymer o te butanediol adipate me te butanediol terephthalate.Kei a ia nga ahuatanga o te PBA (polyadipate-1, 4-butanediol ester diol) me te PBT (polybutanediol terephthalate).He pai te ductility me te elongation i te wehenga, me te pai o te wera wera me te paanga o te mahi.I tua atu, he tino pai te koiora me tetahi o nga mea tino rongonui i roto i te rangahau o nga kirihou koiora me te tono pai rawa atu i te maakete.

Te whakaputanga o te 1, 4-butanediol (BDO) ma te tikanga maleic anhydride
E rua nga tukanga matua mo te hanga BDO na te maleic anhydride.Ko tetahi ko te tukanga hauwai tika o te maleic anhydride i hangaia e Mitsubishi Petrochemical me Mitsubishi Chemical i Japan i te 1970s, e tohuhia ana e te hanga tukutahi o te BDO, THF me te GBL i roto i te tukanga hydrogenation o te maleic anhydride.Ko nga hua o nga hanganga rereke ka taea te tiki ma te whakatika i nga tikanga o te tukanga.Ko tetahi atu ko te tukanga hauwai hau esterification hau o te maleic anhydride i whakawhanakehia e UCC Company me Davey Process Technology Company i te United Kingdom, i whakawhanakehia mai i te hangarau carbonyl synthesis pehanga iti.I te tau 1988, ka oti te arotake ano i te rere o te tukanga, ka whakaarohia te hoahoa ahumahi.I te tau 1989, I WHAKAMAHI TE HANGARAU KI TE KAUPAPA KIMICAL DongSANG o Korea ME DONGGU CHEMICAL Company o Hapani KI te hanga i te 20,000-ton/tau 1, 4-BUtanEDIOL INDUSTRIAL production PLANT.
