Amfani
1,4-Butanediol (BDO)wani muhimmin abu ne na sinadarai na halitta wanda ke da nau'ikan aikace-aikace iri-iri. Manyan hanyoyin amfani sune kamar haka:
Samar da samfurin polyester
- Don haɗa polybutylene terephthalate (PBT): PBT kyakkyawan filastik ne na injiniyan polyester mai thermoplastic. Yana da kyawawan halaye na injiniya, kyakkyawan juriya ga lalata sinadarai, babban rufin lantarki, da kuma ƙarfin kwanciyar hankali mai ƙarfi. Ana amfani da shi sosai a fagen kayan lantarki da na lantarki don ƙera gidaje da haɗin kayan lantarki daban-daban. Wasu sassa a masana'antar kera motoci, kamar maƙallan ƙofar mota da bumpers, ana kuma samar da su ta amfani da kayan PBT.
- Don samar da polyurethane mai zafi (TPU): TPU tana haɗa ƙarfin roba mai yawa tare da sauƙin sarrafawa na filastik. Yana da juriya ga lalacewa, yana jure wa mai, kuma yana jure sanyi. Sau da yawa ana amfani da shi don yin tafin takalma, bututu, wayoyi da murfin kebul, bel ɗin jigilar kaya na masana'antu, da sauransu. 1,4-Butanediol abu ne mai mahimmanci don haɗa TPU, yana ba samfurin kyakkyawan sassauci da halayen tauri.
Yin γ-butyrolactone da N-methylpyrrolidone (NMP)
- γ-butyrolactone: Yana da wani sinadari mai ƙarfi mai narkewa mai ƙarfi, yana da tasirin narkewa mai kyau akan mahaɗan halitta da polymers da yawa. Ana amfani da shi sosai a masana'antar shafawa, tawada, da bugawa da rini. Hakanan shine kayan farko don haɗa kayan ƙanshi daban-daban da tsaka-tsakin magunguna, wanda daga ciki za a iya samo wasu sinadarai masu kyau tare da tsari da ayyuka na musamman daga baya.
- N-methylpyrrolidone: Yana da sinadarin aprotic mai ƙarfi, wanda ke nuna kyakkyawan ikon narkewa ga kayan halitta, marasa narkewa, da polymer da yawa. Yana da matuƙar mahimmanci wajen samar da batirin lithium, wanda ake amfani da shi don narkar da abubuwan ɗaurewa, kayan aiki masu aiki da lantarki, da sauransu. Hakanan yana da mahimman aikace-aikace a cikin samar da magungunan kashe kwari, tsaftacewa ta lantarki, da kuma cirewa da raba su.
Don haɗa tetrahydrofuran (THF): Tetrahydrofuran wani sinadari ne da ake amfani da shi sosai, wanda ke da kyakkyawan narkewa ga mahaɗan halitta da na roba. A cikin dakunan gwaje-gwaje na haɗa kwayoyin halitta da tsarin amsawar sinadarai, ana amfani da shi azaman sinadari don haɓaka amsawa. Bugu da ƙari, shi ma kayan aiki ne na haɗa polytetrahydrofuran (PTMEG). Ana amfani da PTMEG don samar da zare na spandex da polyurethane elastomers, wanda ke samar da tushen kayan aiki mai laushi ga yadi, kayan wasanni masu tsada, da sauran masana'antu.
Aikace-aikace a fannin likitanci: Ana iya amfani da 1,4-Butanediol a matsayin matsakaiciyar magunguna don shiga cikin haɗa wasu ƙwayoyin magunguna. Misali, a cikin matakan haɗa wasu magungunan steroid da maganin rigakafi, ana amfani da ayyukan sinadarai don ginawa da gyara tsarin ƙwayoyin magunguna, yana sauƙaƙa bincike, haɓakawa, da samar da sabbin magunguna.
Marufi da Jigilar Kaya
25KG/Drum ko kuma kamar yadda ake buƙata daga abokin ciniki.
Ya kasance na kayan yau da kullun kuma yana iya isar da kaya ta teku da iska
Ajiyewa da adanawa
Rayuwar shiryayye: Watanni 24 daga ranar ƙera shi a cikin marufi na asali wanda ba a buɗe ba, an adana shi a wuri mai sanyi da bushewa, ba tare da hasken rana kai tsaye ba, ko ruwa.
Ma'ajiyar iska, Busar da ƙananan zafin jiki, An raba shi da sinadarai masu guba, acid.
