1,4-Butanediol (BDO) imvura isina ruvara ine mafuta yakakwezva kutariswa kukuru mumaindasitiri akasiyana-siyana nekuda kwehunhu hwayo hwakasiyana uye kushanduka-shanduka. Iyi makemikari haingosanganiswi nemvura chete, zvichiita kuti ive solvent yakanaka, asi inogonawo kushandiswa semushonga unodzivirira kutonhora usina chepfu, emulsifier yechikafu, uye hygroscopic. Mashandisirwo ayo anosanganisira maindasitiri emishonga nechikafu pamwe nekugadzirwa kwezvinhu zvakasikwa, zvichiita kuti ive reagent yakakosha mumaindasitiri emazuva ano ekugadzira.
Chimwe chezvinhu zvinonyanya kuzivikanwa zve1,4-butanediolkugona kwayo kushanda semusanganiswa. Mundima yemakemikari echisikigo, zvinonyungudutsa zvinoita basa rakakosha mukuita kuti zvinhu zviite nyore uye kunyungudutsa. Kusawirirana kweBDO nemvura kunoita kuti ishandiswe zvinobudirira mumhando dzakasiyana dzemakemikari, kunyanya mugasi chromatography uko inoshanda semvura isingachinji. Hunhu uhwu hwakakosha pakupatsanurwa nekuongororwa kwemisanganiswa yakaoma, zvichiita kuti BDO ive chishandiso chakakosha kune vanoongorora mishonga nevaongorori.
Pamusoro pebasa rayo semusanganiswa, 1,4-butanediol inozivikanwa nekuda kwehunhu hwayo husina chepfu, izvo zvinoita kuti ive yakakodzera indasitiri yechikafu. Semushonga wekudya, BDO inobatsira kudzikamisa musanganiswa waizoparadzana, senge mafuta nemvura. Hunhu uhwu hunonyanya kukosha pakugadzira masosi, zvinonhuhwirira nezvimwe zvigadzirwa zvekudya zvinoda magadzirirwo akafanana uye chitarisiko. Kuchengetedzeka kweBDO kunoita kuti ikwanise kushandiswa pasina kuisa njodzi kuhutano kuvatengi, zvichiwedzera kukwezva kwayo mukushandiswa kwechikafu.
Uye zvakare, hunhu hwe hygroscopic hwe1,4-butanediol inoibvumira kunwa hunyoro kubva munharaunda, zvichiita kuti ive chinhu chinoshanda mumhando dzakasiyana-siyana dzemishonga. Hunhu uhwu hunobatsira zvikuru muindasitiri yemishonga, uko kuchengetedza kugadzikana uye kushanda kwezvinoshandiswa kunokosha. Nekuwedzera BDO mumafomura, vagadziri vanogona kuwedzera hupenyu hwesherufu uye kushanda kwezvigadzirwa zvavo, vachiona kuti zvinosangana nemazinga epamusoro eindasitiri yehutano.
Kuchinja-chinja kwe1,4-butanediolInodarika chikafu nemishonga. Mukugadzirwa kwezvinhu zvakasikwa, BDO ibwe rekuvaka rekugadzira makemikari akasiyana-siyana nezvinhu. Inokwanisa kuita kuti ikwanise kushandurwa kuita polybutylene terephthalate (PBT), thermoplastic inoshandiswa zvakanyanya mukugadzira zvikamu zvemotokari, zvikamu zvemagetsi uye zvigadzirwa zvevatengi. Kuchinja uku kunoratidza basa reBDO senzira yakakosha yekugadzira zvinhu zvine simba repamusoro mukugadzirwa kwemazuva ano.
Sezvo maindasitiri achiramba achichinja-chinja uye achitsvaga mhinduro dzinogara kwenguva refu, kudiwa kwemakemikari asina chepfu, anoshanda zvakawanda akadai se1,4-butanediol kunotarisirwa kukura. Kushandiswa kwayo muzvikamu zvakasiyana-siyana zvakaita sezvekudya, mishonga nesainzi yezvinhu zvinoratidza kukosha kwayo mumabasa emakemikari emazuva ano. Nekuenderera mberi nekutsvaga nekuvandudza, kushandiswa kweBDO kunogona kuwedzera, zvichigadzira nzira yezvigadzirwa zvitsva nemhinduro dzinosangana nezvinodiwa nenyika iri kuchinja nguva dzose.
Mukupedzisa,1,4-butanediol imusanganiswa unoshamisa une basa rakakosha mumaindasitiri akasiyana-siyana. Hunhu hwayo semusanganiswa, mudziviriri wechando usina chepfu, musanganiswa wezvekudya uye musanganiswa we hygroscopic zvinoita kuti ive chinhu chakakosha mumaindasitiri emishonga nezvekudya pamwe nekugadzira organic. Sezvatinoramba tichiongorora kugona kwemusanganiswa uyu unoshanduka-shanduka, zviri pachena kuti 1,4-butanediol icharamba ichiita basa guru mukusimudzira makemikari emazuva ano nemaindasitiri.
