1,4-Butanediol (BDO) imvura ine mafuta isina ruvara iyo yakakwezva kutarisisa kukuru mumaindasitiri akasiyana nekuda kweiyo yakasarudzika midziyo uye kuita zvakasiyana. Haisi musanganiswa chete wemusanganiswa uyu nemvura, zvichiita kuti ive munyungudutsa wakanakisa, asi unogona zvakare kushandiswa sechinhu chisina chepfu chinodzivirira kutonhora, emulsifier yechikafu, uye hygroscopic agent. Zvishandiso zvaro zvinotora maindasitiri emishonga uye ezvekudya pamwe neorganic synthesis, zvichiita kuti ive yakakosha kemikari reagent mumagadzirirwo emazuva ano ekugadzira.
Chimwe chezvinhu zvinonyanya kukosha zve1,4-butanediolkugona kwayo kuita semunyungudutsa. Mumunda we organic chemistry, zvinonyungudutsa zvinoita basa rakakosha mukufambisira mabatiro uye nekunyungudutsa zvinhu. BDO's miscibility nemvura inobvumira kuti ishandiswe zvinobudirira mumhando dzakasiyana siyana dzemakemikari, kunyanya mugasi chromatography uko inoshanda semvura yakamira. Ichi chivakwa chakakosha pakupatsanura uye kuongororwa kwemisanganiswa yakaoma, zvichiita kuti BDO ive chishandiso chakakosha chemakemikari nevaongorori.
Mukuwedzera kune basa rayo sechinhu chinonyungudutsa, 1,4-butanediol inozivikanwa nokuda kwemaitiro ayo asina chepfu, iyo inoita kuti ive yakanaka kune indasitiri yezvokudya. Sechikafu emulsifier, BDO inobatsira kudzikamisa misanganiswa yaizoparadzana, semafuta nemvura. Ichi chivakwa chinonyanya kukosha pakugadzira sosi, condiments uye zvimwe zvigadzirwa zvekudya zvinoda kuenderana magadzirirwo uye chitarisiko. BDO's chengetedzo mbiri inova nechokwadi chekuti inogona kushandiswa pasina kuisa njodzi dzehutano kune vatengi, ichiwedzera kuwedzera kukwezva kwayo mumashandisirwo echikafu.
Uyezve, iyo hygroscopic chimiro che1,4-butanedioNdinobvumira kuti itore unyoro kubva kune zvakatipoteredza, zvichiita kuti ive chinhu chinoshanda mumhando dzakasiyana-siyana dzekugadzirisa. Ichi chivakwa chinonyanya kubatsira muindasitiri yemishonga, uko kuchengetedza kugadzikana uye kushanda kwezvishandiso zvinoshandiswa zvakakosha. Nekuwedzera BDO kune maumbirwo, vagadziri vanogona kuwedzera hupenyu hwesherufu uye kushanda kwezvigadzirwa zvavo, kuve nechokwadi kuti vanosangana nemhando yepamusoro yeindasitiri yehutano.
Izvo zvakasiyana-siyana zve1,4-butanediolzvinopfuura zvokudya nemishonga. Mune organic synthesis, BDO chivakwa chekuvaka chekugadzirwa kweakasiyana emakemikari uye zvinhu. Iyo inokwanisa kuita polymerization maitiro kuitira kuti ishandurwe kuita polybutylene terephthalate (PBT), iyo thermoplastic inoshandiswa zvakanyanya mukugadzirwa kwezvikamu zvemotokari, zvikamu zvemagetsi uye zvigadzirwa zvevatengi. Shanduko iyi inosimbisa basa reBDO seyakakosha-inoshanda zvinhu zvemberi zvekugadzirwa kwemazuva ano.
Sezvo maindasitiri ari kuramba achishanduka uye kutsvaga mhinduro dzakasimba, kudiwa kweasina chepfu, akawanda-anoshanda makemikari akadai se1,4-butanediol anotarisirwa kukura. Mashandisirwo ayo mundima dzakasiyana sechikafu, mishonga uye sainzi yemidziyo inosimbisa kukosha kwayo mumaitiro emazuva ano emakemikari. Nekuenderera mberi nekutsvagisa nekusimudzira, zvinogona kushandiswa neBDO zvinogona kuwedzera, zvichigadzira nzira yezvigadzirwa zvitsva nemhinduro dzinosangana nezvinodiwa nenyika inogara ichichinja.
Mukupedzisa,1,4-butanediol ikomisheni inoshamisa inoita basa rakakosha mumaindasitiri akasiyana. Hunhu hwayo sechinhu chinonyungudutsa, isiri-chepfu antifreeze, emulsifier yechikafu uye hygroscopic agent inoita kuti ive yakakosha sosi mumaindasitiri emishonga uye ezvekudya pamwe neiyo organic synthesis. Sezvatinoenderera mberi nekuongorora zvingaita zvemusanganiswa uyu wakasiyana-siyana, zviri pachena kuti 1,4-butanediol icharamba ichiita basa rinokosha mukugadzirwa kwemakemikari emazuva ano uye indasitiri.
