Ikoreshwa
1, 4-butanediol ikoreshwa cyane.Muri Amerika no mu Burayi bw’iburengerazuba ku gice kirenga kimwe cya kabiri cy’umusaruro wa tetrahydrofuran, ugakurikirwa n’umusaruro wa γ-butanolactone na polybutylene terephthalate, uwanyuma ni plastiki y’ubwubatsi itera imbere byihuse;1, 4-butanediol ikoreshwa nk'iyagura urunigi n'ibikoresho fatizo bya polyester kugirango habeho umusaruro wa elastomeri ya polyurethane na plastike yoroshye ya polyurethane;Esters ya 1, 4-butanediol ninyongera nziza ya selile, polyvinyl chloride, polyacrylates na polyester.1.Irashobora kandi gutegurwa N-methylpyrrolidone, N-vinyl pyrrolidone nizindi nkomoko ya pyrrolidone, ikoreshwa kandi mugutegura vitamine B6, imiti yica udukoko, imiti yica udukoko hamwe nudukoko dutandukanye, amashanyarazi, amavuta, amavuta meza, ibyuma byangiza, amashanyarazi hamwe ninganda zikoresha amashanyarazi.
Reagent yo gusesengura imiti;ikoreshwa nkigisubizo gihagaze kuri gazi chromatografiya.Ikoreshwa nka antifreeze, idafite uburozi, emulisiferi yibiryo, ibyuka byangiza, kugirango bihindurwe.Imiti, inganda.

Ububiko
Yabitswe ahantu hakonje, ihumeka, ububiko kure yinzu, yaje kubaho.Ibikoresho byo kuzimya umuriro hamwe nibikoresho byabitswe bifunze birahari.Ibyuma byoroheje, aluminium cyangwa ibikoresho byumuringa birahari.
Koresha aluminiyumu, ibyuma bidafite ingese, ibyuma cyangwa plastike cyangwa ibikoresho byaka kugirango ubike kandi utwarwe.Igice gifite ubushyuhe ntarengwa bwa 20 ° C kigomba kuba cyuzuyemo ibintu hamwe na tebes.
