Ukusetshenziswa kwe-butanediol ku-cosmetics
I-Butanediol, ikakhulukazi i-acetylene ne-formaldehyde njengezinto zokusetshenziswa.Isetshenziswa njenge-chain extender ekukhiqizeni i-polybutylene terephthalate ne-polyurethane, futhi njengento ebalulekile eluhlaza ye-tetrahydrofuran, i-γ-butyrolactone, imithi kanye ne-organic synthesis.Ngenxa yokuthi i-polybutylene terephthalate iwuhlobo lwe-polyester enezakhiwo ezinhle, isidingo samapulasitiki obunjiniyela sikhula ngokushesha.

Ikhemikhali yaselabhorethri enobuthi kakhulu - i-propargyl alcohol
I-Propargyl Utshwala, ifomula yamangqamuzana C3H4O, isisindo samangqamuzana 56. Uketshezi olungenambala olusobala, oluguquguqukayo olunephunga elimnandi, olunobuthi, ukucasuka okukhulu esikhumbeni nasemasweni.I-intermediate in organic synthesis.Ikakhulu esetshenziselwa ukuhlanganiswa kwezidakamizwa ezilwa namagciwane kanye ne-anti-inflammatory sulfadiazine;Ngemuva kwe-hydrogenation eyingxenye, i-propylene alcohol ingakhiqiza i-resin, futhi ngemva kwe-hydrogenation ephelele, i-n-propanol ingasetshenziswa njengempahla eluhlaza ye-anti-tuberculosis drug ethambutol, kanye neminye imikhiqizo yamakhemikhali nemithi.Ingakwazi ukuvimbela i-asidi ku-iron, ithusi ne-nickel nezinye izinsimbi, ezisetshenziswa njengesikhiphi sokugqwala.Kusetshenziswa kakhulu ekukhishweni kukawoyela.Ingasetshenziswa futhi njenge-solvent, i-stabilizer yama-hydrocarbon e-chlorinated, i-herbicide kanye nesibulala-zinambuzane.Ingasetshenziselwa ukukhiqizwa kwe-acrylic acid, i-acrolein, i-2-aminopyrimidine, i-γ-picauline, i-vitamin A, i-stabilizer, i-corrosion inhibitor nokunye.
Amanye amagama: i-propargyl alcohol, i-2-propargyl - i-1-alcohol, i-2-propargyl alcohol, i-propargyl alcohol acetylene methanol.

I-Propargyl izokwenziwa i-polymerize futhi iqhume
Inqubo yokuqala isuselwe ku-propargyl alcohol njenge-solvent, i-KOH njengesisekelo, ukusabela kokushisisa ukuze kutholwe okuhlosiwe.Ukusabela ngaphandle kwezimo ze-solvent dilution kuzoba ukungcola okuncane, ukusabela kuhlanzekile.
Uma kucatshangelwa i-polymerization enamandla engase ibe khona kanye nokubola okuqhumayo kwama-alkynes etheminali, I-Amgen's Hazard Evaluation Lab (HEL) yangenela ukuze yenze ukuhlola kokuphepha futhi isize ekuthuthukiseni inqubo ngaphambi kokukala kuze kufike kumalitha angu-2 okusabela.
Ukuhlolwa kwe-DSC kukhombisa ukuthi ukusabela kuqala ukubola ku-100 ° C futhi kukhulule amandla angama-3667 J/g, kuyilapho i-propargyl alcohol ne-KOH ndawonye, nakuba amandla ehla aze afike ku-2433 J/g, kodwa izinga lokushisa lokubola nalo lehla liye ku-85 ° C, futhi izinga lokushisa lenqubo lisondele kakhulu ku-60 °C, ingozi yokuphepha inkulu.

1,4-butanediol (BDO) kanye nokulungiswa kwayo kwePBAT yepulasitiki ebolayo
1, 4-butanediol (BDO);I-PBAT iyipulasitiki ekwazi ukubola nge-thermoplastic, eyi-copolymer ye-butanediol adipate ne-butanediol terephthalate.Inezici ze-PBA (i-polyadipate-1, i-4-butanediol ester diol) ne-PBT (i-polybutanediol terephthalate).Ine-ductility enhle kanye nobude ngesikhathi sekhefu, kanye nokumelana nokushisa okuhle nokusebenza komthelela.Ngaphezu kwalokho, inokubola okuhle kakhulu kwe-biodegradability futhi ingenye yezinto ezidume kakhulu ezibolayo ocwaningweni lwamapulasitiki abolayo kanye nokusetshenziswa okuhle kakhulu emakethe.

Ukukhiqizwa kwe-1, 4-butanediol (BDO) ngendlela ye-maleic anhydride
Kunezinqubo ezimbili eziyinhloko zokukhiqizwa kwe-BDO nge-anhydride ye-maleic.Enye inqubo ye-hydrogenation eqondile ye-maleic anhydride eyakhiwe yi-Mitsubishi Petrochemical and Mitsubishi Chemical e-Japan ngeminyaka yawo-1970, ebonakala ngokukhiqizwa ngesikhathi esisodwa kwe-BDO, THF kanye ne-GBL ohlelweni lwe-hydrogenation lwe-maleic anhydride.Imikhiqizo yezingoma ezihlukene ingatholakala ngokulungisa izimo zenqubo.Enye inqubo ye-gas esterification hydrogenation ye-maleic anhydride eyakhiwe yi-UCC Company kanye ne-Davey Process Technology Company e-United Kingdom, ethuthukiswe kusukela kubuchwepheshe obuphansi be-carbonyl synthesis.Ngo-1988, ukuhlolwa kabusha kokugeleza kwenqubo kwaqedwa futhi nomklamo wezimboni wahlongozwa.Ngo-1989, UBUCHWEPHESHE BATHUNYELWA E-DongSANG CHEMICAL COMPANY YASE-Korea KANYE NE-DONGGU CHEMICAL Company yase-Japan UKUZE KWAKHIWE I-20,000-TON/year 1, 4-BUtanEDIOL INDUSTRIAL Production PLANT.

Inqubo yokukhiqiza utshwala be-Propargyl kanye nokuhlaziywa kwemakethe
I-Propargyl alcohol (PA), ngokwekhemikhali eyaziwa ngokuthi i-2-propargyl alcohol-1-ol, iwuketshezi olungenambala, oluguquguquka ngokulingene olunephunga elimnandi leqabunga.Ukuminyana kungu-0.9485g/cm3, indawo encibilikayo: -50 ℃, indawo abilayo: 115 ℃, i-flash point: 36 ℃, evuthayo, eqhumayo: encibilika emanzini, i-chloroform, i-dichloroethane, i-methanol, i-ethanol, i-ethyl ether, i-dioxane, i-tetrahydrone, I-pyridine, inyibilika kancane ku-carbon tetrachloride, engancibiliki ku-aliphatic hydrocarbon.Utshwala be-Propargyl buyinto ebalulekile yamakhemikhali eluhlaza, esetshenziswa kabanzi kwezokwelapha, imboni yamakhemikhali, i-electroplating, i-pesticide, insimbi, i-petroleum neminye imikhakha.
Isicelo
Isebenza ngokukhethekile ekukhiqizeni utshwala be-propargyl, i-1,4 butynediol kanye ne-3-chloropropyne
