Butenediol uye 1,4-Butanediolndiwo maviri akasiyana emakemikari makomisheni anoshandiswa mune akasiyana maapplication muindasitiri, emishonga, uye zvikamu zvekugadzira. Pasinei nemazita avo akafanana uye chimiro chemolecular, aya makomisheni maviri ane misiyano yakawanda inovasiyanisa kubva kune mumwe.
Chekutanga,Butenediol uye 1,4-Butanediolvane mafomula akasiyana siyana. Butenediol ine formula, C4H6O2, nepo 1,4-Butanediol ine fomula yeC4H10O2. Uyu mutsauko muchimiro chemolecular uye fomula unokanganisa iwo emuviri nemakemikari zvimiro, senge kunyunguduka uye kubikira mapoinzi, solubility, uye reactivity.
Chechipiri,Butenediol uye 1,4-Butanediolzvine mashandisirwo akasiyana uye mashandisirwo. Butenediol inonyanya kushandiswa mukugadzira polyester uye polyurethane resins, adhesives, plasticizers, uye sechinhu chinonyungudutsa chependi uye machira. Kusiyana neizvi, 1,4-Butanediol inoshandiswa sechikafu chekugadzirwa kwemakemikari akawanda, kusanganisira gamma-butyrolactone (GBL), tetrahydrofuran (THF), uye polyurethanes. Pamusoro pezvo, inoshandiswa mukugadzira zvinhu zvemotokari, zvemagetsi, zvemishonga, uye zvekuzora.
Chechitatu,Butenediol uye 1,4-Butanediolvane huturu hwakasiyana uye njodzi dzine chekuita nekushandisa kwavo. Butenediol inorondedzerwa sechinhu chinogumbura ganda uye maziso uye inogona kukonzera kutsamwa kwekufema kana yakafemerwa. Kune rumwe rutivi, 1,4-Butanediol inorondedzerwa sechinhu chinogona kukonzera kenza uye mutagen uye inoisa mungozi yehutu hwakanyanya kuvanhu kana ikabatwa kana kuputika.
Pakupedzisira,Butenediol uye 1,4-Butanediolvane maitiro akasiyana ekugadzira. Kugadzirwa kweButenediol kunosanganisira kuita kwemaleic anhydride nedoro, senge ethylene glycol kana propylene glycol. Kugadzirwa kwe1,4-Butanediol, kune rumwe rutivi, kunosanganisira hydrogenation ye succinic acid, iyo inowanikwa kubva kune anaerobic fermentation yezvinhu zvinogona kuvandudzwa, zvakadai segorosi starch kana shuga.
Mukupedzisa,Butenediol uye 1,4-Butanediolndiwo maviri akasiyana emakemikari makomisheni ane akasiyana mamorekuru mafomula, mashandisiro, chepfu, njodzi, uye maitiro ekugadzira. Nepo vachigovana zvimwe zvakafanana, sekushandisa kwavo mukugadzira polyurethanes, vane zvimiro zvakasiyana zvinoita kuti vakwanise kushandiswa kwakasiyana. Izvo zvakakosha kuti unzwisise misiyano iyi kuve nechokwadi chekushandisa kwavo kwakachengeteka uye kwakanaka mumaindasitiri akasiyana uye maapplication.
