Chii chinonzi gamma-valerolactone chinoshandiswa?
Y-valerolactone (GVL), isina ruvara-inonyungudika mvura organic komboni, yakwezva kutarisisa kwakawanda mumakore achangopfuura nekuda kwehuwandu hwayo hwekushandisa. Iyo cyclic ester, kunyanya lactone, ine fomula C5H8O2. GVL inoonekwa zviri nyore nekunhuhwirira kwayo uye kuravira.
GVL inonyanya kushandiswa sechinhu chinonyungudutsa mumaindasitiri akasiyana siyana anosanganisira mishonga, zvizorwa, zvekurima uye petrochemicals. Hunhu hwayo hwakasiyana uye huchetura hwakaderera hunoita kuti ive sarudzo yekutanga kutsiva zvechinyakare zvinonyungudutsa zvinogona kukuvadza hutano hwevanhu kana nharaunda. Mukuwedzera, GVL inoshandiswawo sechigadziro chekugadzirisa kwemhando dzakasiyana-siyana dzakakosha.
Imwe yeakakosha mashandisirwo eGVL iri muindasitiri yemishonga seyakagadzikana uye inoshanda zvinonyungudutsa. Mishonga yakawanda uye inoshanda mishonga yemishonga (APIs) inogadzirwa uye inogadzirwa uchishandisa organic solvents. Nekuda kwehunhu hwayo hwakanaka, GVL yave nzira inovimbisa kune zvinowanzoshandiswa zvinonyungudutsa zvakaita sedimethyl sulfoxide (DMSO) uye N, N-dimethylformamide (DMF). Inogona kunyungudutsa huwandu hwakawanda hwemishonga uye APIs, ichifambisa kuumbwa kwavo nekugadzirisa uku ichideredza njodzi dzinogona kuitika dzine chekuita nezvimwe zvinonyungudutsa.
Muindasitiri yezvizorwa,GVLinoshandiswa seyakasvibira solvent yezvinangwa zvakasiyana. Inowanzo shandiswa mukutora, kucheneswa uye synthesis yezvizorwa zvigadzirwa. GVL inopa mhinduro ine hushamwari hwezvakatipoteredza kupfuura zvinonyungudutsa zvechinyakare, izvo zvinowanzoburitsa zvinokuvadza nezvinogadzirwa. Hunhu hwayo hunyoro uye kushomeka kweganda kushoma kunoitawo kuti ive sarudzo yakachengeteka mukugadzirwa kwezvizoro.
Zvekurima ndeimwe ndima yekushandisa yeGVL. Inoshandiswa sechinhu chinonyungudutsa muzvigadzirwa zvekudzivirira zvipembenene, mishonga yesora uye fungicides. GVL inogona kunyatso kunyungudika uye kuendesa izvi zvinongedzo zvinosanganisa kune yakanangwa chipenyu uku ichideredza mhedzisiro yakaipa. Pamusoro pezvo, iyo yakaderera mhute pressure uye yakakwira yekubikira poindi yeGVL inoita kuti ive yakakodzera kugadzirwa uye kuendeswa kweagrochemicals.
GVL's versatility inowedzera kune petrochemical indasitiri. Inoshandiswa sechinhu chinonyungudutsa uye co-solvent mumhando dzakasiyana-siyana, kusanganisira kubviswa kwemakemikari anokosha kubva kubiomass uye petroleum-derived feedstocks.GVLyakaratidza mukana wekushandiswa mukugadzirwa kwemafuta ehupenyu nemakemikari anovandudzwa, achipa mamwe maitiro akasvibira uye akasimba kune zvigadzirwa zvepetroleum.
Pamusoro pekuva solvent, GVL inogona kushandiswa sechinhu chekutanga chekugadzirwa kwemishonga yakakosha. Inogona kushandurwa kemikari kuita gamma-butyrolactone (GBL), komisheni inoshandiswa zvakanyanya mukugadzirwa kwemapolymer, resin uye mishonga yemishonga. Shanduko yeGVL kuita GBL inosanganisira nzira iri nyore uye inoshanda, ichiita kuti ive mumiriri anoyevedza wekushandisa maindasitiri.
Muchidimbu, γ-valerolactone (GVL) inosanganiswa nemhando dzakasiyana siyana dzekushandisa. Nekuda kwekuderera kwayo muchetura uye kuita kwakanaka, kushandiswa kwayo sechinhu chinonyungudutsa mumishonga yemishonga, cosmetic, yekurima uye petrochemical industries yakagadziridzwa zvakanyanya. GVL inopa inogoneka uye inoshanda dzimwe nzira kune yechinyakare zvinonyungudutsa, ichikurudzira yakasvibira uye yakachengeteka maitiro. Uyezve, maGVL anogona kushandurwa kuita makomisheni akakosha, zvichiwedzera kuwedzera kugona kwavo uye kukosha kwehupfumi. Iko kugona uye kukosha kweGVL kunotarisirwa kukura mumakore anotevera sezvo maindasitiri ari kuramba achitsvaga mhinduro dzakasimba.
