Codsiga butanediol ee alaabta la isku qurxiyo
Butanediol, inta badan acetylene iyo formaldehyde sida alaabta ceeriin.Waxaa loo isticmaalaa sidii silsilad fidsan oo loogu talagalay soo saarista polybutylene terephthalate iyo polyurethane, iyo sida alaabta ceeriin ee muhiimka ah ee tetrahydrofuran, γ-butyrolactone, daawada iyo isku-dhafka organic.Sababtoo ah polybutylene terephthalate waa nooc ka mid ah polyester-ka leh sifooyin wanaagsan, baahida balaastikada injineernimada ayaa si degdeg ah u kordheysa.

Kiimikada shaybaadhka sunta ah ee aad u sunta ah - khamriga propargyl
Propargyl Alcohol, formula molecular C3H4O, molecular weight 56. Dareere hufan oo aan midab lahayn, kacsan oo leh ur xun, sun ah, cuncun halis ah maqaarka iyo indhaha.Dhexdhexaad ka ah isku-dhafka organic.Inta badan loo isticmaalo isku-darka daawooyinka bakteeriyada iyo anti-bararka sulfadiazine;Ka dib qayb ahaan hydrogenation, alkolada propylene waxay soo saari kartaa resin, ka dib hydrogenation dhamaystiran ka dib, n-propanol waxaa loo isticmaali karaa sida alaabta ceeriin ee daawada qaaxada ee ethambutol, iyo sidoo kale kiimikooyinka kale ee daawooyinka.Waxay u diidi kartaa aashitada birta, naxaasta iyo nikkelka iyo biraha kale ee daxalka, loo isticmaalo ka saarida miridhku.Si ballaaran loo isticmaalo soo saarista saliidda.Waxa kale oo loo isticmaali karaa dareere ahaan, xasiliye ee hydrocarbons koloriin leh, herbicide iyo cayayaanka.Waxaa loo isticmaali karaa soo saarista acrylic acid, acrolein, 2-aminopyrimidine, γ-picauline, vitamin A, stabilizer, daxalka inhibitor iyo wixii la mid ah.
Magacyo kale: khamriga propargyl, 2-propargyl - 1-khamri, 2-alkolada propargyl, propargyl alkohol acetylene methanol.

Propargyl ayaa polymerize doona oo qarxi doonta
Habka bilawga ah wuxuu ku salaysan yahay aalkolada propargyl sida dareeraha, KOH oo saldhig u ah, falcelinta kuleylka si loo helo bartilmaameedka.Dareen-celinta iyada oo aan lahayn xaaladaha qasitaanku waxay noqon doontaa wasakh yar, falcelintu waa nadiif.
Iyadoo la tixgalinayo polymerization katalytic ee suurtogalka ah iyo burburka qarxa ee terminal alkynes, Amgen's Hazard Evaluation Lab (HEL) ayaa u soo galay si uu u sameeyo qiimeynta badbaadada iyo caawinta habka wanaajinta ka hor inta aan la miisaamin ilaa 2 litir oo falcelinta.
Tijaabada DSC waxay muujinaysaa in falcelintu ay bilaabato inay burburto 100 ° C oo ay sii deyso tamarta 3667 J / g, halka alkolada propargyl iyo KOH wadajir ah, inkastoo tamartu ay hoos ugu dhacdo 2433 J / g, laakiin heerkulka burburku wuxuu sidoo kale hoos ugu dhacayaa 85 ° C, iyo heerkulka habka ayaa aad ugu dhow 60 °C, khatarta badbaadada ayaa ka weyn.

1,4-butanediol (BDO) iyo diyaarintiisa PBAT balaastiig-bidegradable
1, 4-butanediol (BDO);PBAT waa balaastiig heerkul-ku-balaastig ah, kaas oo ah copolymer butanediol adipate iyo butanediol terephthalate.Waxay leedahay sifooyinka PBA (polyadipate-1, 4-butanediol ester diol) iyo PBT (polybutanediol terephthalate).Waxay leedahay ductility wanaagsan iyo elongation ee nasashada, iyo sidoo kale iska caabin kulaylka wanaagsan iyo waxqabadka saamaynta.Intaa waxaa dheer, waxay leedahay biodegradability aad u fiican oo waa mid ka mid ah qalabka ugu caansan ee biodegradable ee cilmi-baarista bacaha noolaha iyo codsiga ugu fiican ee suuqa.

Wax soo saarka 1, 4-butanediol (BDO) ee habka anhydride lab
Waxaa jira laba hab oo waaweyn oo loogu talagalay soo saarista BDO ee maleic anhydride.Mid waa habka tooska ah ee hydrogenation-ka ee anhydride-ka lab ah ee ay soo saareen Mitsubishi Petrochemical iyo Mitsubishi Chemical ee Japan 1970-meeyadii, taas oo lagu garto wax soo saarka isku mar ah ee BDO, THF iyo GBL ee habka hydrogenation of anhydride maleic.Alaabooyinka ka kooban noocyo kala duwan ayaa lagu heli karaa iyadoo la hagaajinayo xaaladaha habka.Midda kale waa habka gaaska esterification hydrogenation of maleic anhydride oo ay soo saartay Shirkadda UCC iyo Shirkadda Davey Process Technology ee Boqortooyada Midowday, kaas oo laga sameeyay tignoolajiyada isku-dhafka karbonyl ee cadaadiska hooseeya.Sannadkii 1988-kii, dib-u-qiimaynta habka socodka ayaa la dhammaystiray waxaana la soo jeediyay naqshadaynta warshadaha.1989-kii, TECHNOLOGY-KA waxa loo Wareejiyay Shirkadda Kiimikada DongSANG ee Kuuriya iyo Shirkadda DONGGU ee Kiimikada ee Japan si loo dhiso 20,000-TON/sanad 1, 4-BUtanEDIOL warshad wax soo saar ah.
