    Kugwiritsa ntchito

    1, 4-butanediol imagwiritsidwa ntchito kwambiri.Ku United States ndi kumadzulo kwa Ulaya kwa zaka zoposa theka la kupanga tetrahydrofuran, kutsatiridwa ndi kupanga γ-butanolactone ndi polybutylene terephthalate, yotsirizirayi ndi mapulasitiki opangidwa mofulumira;1, 4-butanediol imagwiritsidwa ntchito ngati unyolo wowonjezera ndi poliyesitala yaiwisi yopanga ma polyurethane elastomers ndi mapulasitiki ofewa a thovu a polyurethane;Ma esters a 1, 4-butanediol ndi zowonjezera zabwino za cellulose, polyvinyl chloride, polyacrylates ndi polyesters.1, 4-butanediol ili ndi kusinthasintha kwabwino kwa hygroscopic, ingagwiritsidwe ntchito ngati chofewa cha gelatin ndi madzi otsekemera, cellophane ndi mankhwala ena omwe si a pepala.Angathenso kukonzekera N-methylpyrrolidone, N-vinyl pyrrolidone ndi zina zotumphukira pyrrolidone, komanso ntchito yokonza vitamini B6, mankhwala, herbicides ndi zosiyanasiyana ndondomeko solvents, plasticizers, lubricants, humidifiers, softness, zomatira ndi electroplating makampani brightener.
    A reagent kwa kusanthula mankhwala;amagwiritsidwa ntchito ngati njira yoyima ya chromatography ya gasi.Amagwiritsidwa ntchito ngati zosungunulira, zopanda poizoni antifreeze, emulsifier chakudya, kuyamwa chinyezi, popanga organic synthesis.Pharmaceutical, food industry.
