Ubonelelo ngefektri CAS 110-63-4 1,4-Butanediol Ulwelo olungenaMbala olunoBunyulu obuPhezulu
Ukusetyenziswa
I-1, i-4-butanediol isetyenziswa ngokubanzi.EUnited States naseNtshona Yurophu ngaphezu kwesiqingatha sokuveliswa kwe-tetrahydrofuran, elandelwa yimveliso ye-γ-butanolactone kunye ne-polybutylene terephthalate, le yokugqibela yiplastiki yobunjineli ekhula ngokukhawuleza;I-1, i-4-butanediol isetyenziselwa i-chain extender kunye ne-polyester ekrwada ukuveliswa kwe-polyurethane elastomers kunye neeplastiki ezithambileyo ze-polyurethane foam;I-esters ye-1, i-4-butanediol izongezo ezilungileyo ze-cellulose, i-polyvinyl chloride, i-polyacrylates kunye ne-polyesters.I-1, i-4-butanediol inokuguquguquka okuhle kwe-hygroscopic, ingasetyenziselwa njenge-gelatin softener kunye ne-absorbent yamanzi, i-cellophane kunye nenye i-arhente yonyango engeyiyo yephepha.Ingalungiswa kwakhona i-N-methylpyrrolidone, i-N-vinyl pyrrolidone kunye nezinye izinto eziphuma kwi-pyrrolidone, nazo zisetyenziselwa ukulungiswa kwe-vitamin B6, izibulala-zinambuzane, izibulala-zinambuzane kunye neenkqubo ezahlukeneyo zokunyibilikisa, iiplastiki, izithambiso, izinto zokuthambisa, ukuthamba, izinto zokuncamathelisa kunye ne-electroplating industry brightener.
I-reagent yohlalutyo lweekhemikhali;isetyenziswe njengesisombululo esimileyo sechromatography yerhasi.Isetyenziswa njenge-solvent, i-antifreeze engeyona inetyhefu, i-emulsifier yokutya, i-absorbent yokufuma, kwi-organic synthesis.Amachiza, ishishini lokutya.

Iimeko zokuGcina
Igcinwe kwindawo epholileyo, engena umoya, indawo yokugcina kude nendlu, yaba khona.Izixhobo zokulwa nomlilo kunye nezikhongozeli zamanzi ezifanelekileyo ezitywiniweyo ziyafumaneka.Izikhongozeli zentsimbi, ialuminiyam okanye ubhedu ziyafumaneka.
Sebenzisa i-aluminium, insimbi engenasici, intsimbi okanye iitanki zeplastiki okanye izinto ezinokutsha zokugcina kunye nokuthutha.I-compartment enobushushu obuphezulu be-20 ° C kufuneka izaliswe ngezikhongozeli kunye neetyhubhu.
