Isetyenziselwa ntoni i-gamma-valerolactone?
I-Y-valerolactone (GVL), i-compound engenambala yamanzi e-soluble organic compound, iye yatsala ingqalelo enkulu kwiminyaka yamuva ngenxa yoluhlu olubanzi lwezicelo.I-ester ye-cyclic, ngokukodwa i-lactone, kunye ne-formula C5H8O2.I-GVL ichongwa ngokulula ngevumba layo elahlukileyo kunye nencasa.
I-GVL isetyenziswa ngokuyintloko njenge-solvent kumashishini ahlukeneyo aquka amayeza, izithambiso, ezolimo kunye ne-petrochemicals.Iimpawu zayo ezizodwa kunye netyhefu ephantsi zenza ukuba kube yinto yokuqala yokukhetha ukuthatha indawo ye-solvents yendabuko enokuba yingozi kwimpilo yabantu okanye kwindalo.Ukongeza, i-GVL iphinda isetyenziswe njenge-precursor ye-synthesis yeentlobo ezahlukeneyo zeekhompawundi ezixabisekileyo.
Esinye sezicelo eziphambili ze-GVL kushishino lwamayeza njenge-solvent ezinzileyo nesebenzayo.Amachiza amaninzi kunye nezithako ezisebenzayo zamachiza (APIs) zenziwe kwaye zenziwe kusetyenziswa i-solvents eziphilayo.Ngenxa yeepropati zayo ezithandekayo, i-GVL iye yaba yindlela ethembisayo kwi-solvents esetyenziswa ngokuqhelekileyo njenge-dimethyl sulfoxide (DMSO) kunye ne-N, N-dimethylformamide (DMF).Iyakwazi ukutshabalalisa uluhlu olubanzi lwamachiza kunye ne-APIs, iququzelele ukuhlanganiswa kunye nokuqulunqwa kwayo ngelixa inciphisa ingozi enokubakho ehambelana nezinye izinyibilikisi.
Kwishishini lokuthambisa,GVLisetyenziswa njengesinyibilikisi esiluhlaza ngeenjongo ezahlukeneyo.Ngokuqhelekileyo isetyenziselwa ukukhutshwa, ukuhlanjululwa kunye nokuhlanganiswa kwezithako zokuthambisa.I-GVL inikezela ngesisombululo esisingqongileyo ngakumbi kunezinyibilikisi zemveli, ezihlala zivelisa imveliso eyingozi.Ivumba layo elithambileyo kunye nokubanakho ukucaphuka kwesikhumba okuncinci kwenza kube lukhetho olukhuselekileyo kwiindlela zokuthambisa.
EzoLimo yenye indawo yesicelo se-GVL.Isetyenziswa njengesinyibilikisi kwiimveliso zokulawula izinambuzane, imichiza yokutshabalalisa ukhula kunye nemichiza yokungunda.I-GVL inokunyibilikisa ngokufanelekileyo kwaye ihambise ezi zithako ezisebenzayo kwizinto ezijoliswe kuzo ngelixa inciphisa iziphumo ezibi.Ukongezelela, uxinzelelo oluphantsi lomphunga kunye neqondo eliphezulu lokubilisa le-GVL lenza ukuba lilungele ukuqulunqwa kunye nokuhanjiswa kweekhemikhali ze-agrochemicals.
Ukuguquguquka kwe-GVL kukwanwenwela kushishino lwepetrochemical.Isetyenziswe njenge-solvent kunye ne-co-solvent kwiinkqubo ezahlukeneyo, kubandakanywa ukutsalwa kweekhemikhali ezixabisekileyo kwi-biomass kunye ne-petroleum-derived feedstocks.GVLibonise amandla okusetyenziswa kwimveliso ye-biofuels kunye neekhemikhali ezivuselelekayo, ukubonelela ngeendlela eziluhlaza kunye nezizinzileyo kwiimveliso zepetroleum.
Ukongeza ekubeni yi-solvent, i-GVL ingasetyenziselwa njengento yokuqala yokwenziwa kwezinto ezixabisekileyo.Iyakwazi ukuguqulwa ngamakhemikhali kwi-gamma-butyrolactone (GBL), i-compound esetyenziswa ngokubanzi kwimveliso yeepolymers, i-resins kunye namayeza.Ukuguqulwa kwe-GVL ukuya kwi-GBL kubandakanya inkqubo elula nesebenzayo, eyenza ibe ngumgqatswa onomtsalane kwizicelo zamashishini.
Isishwankathelo, i-γ-valerolactone (i-GVL) yinto edibeneyo yezinto eziphilayo ezinoluhlu olubanzi lokusetyenziswa.Ngenxa yobutyhefu obuphantsi kunye nokusebenza kakuhle, ukusetyenziswa kwayo njenge-solvent kwi-pharmaceutical, i-cosmetic, imveliso yezolimo kunye ne-petrochemical iphuhliswe kakhulu.I-GVL ibonelela ngeendlela ezizinzileyo nezisebenzayo kwizinyibilikisi zemveli, ukukhuthaza iindlela eziluhlaza nezikhuselekileyo.Ngaphaya koko, ii-GVLs zinokuguqulwa zibe ziikhompawundi ezixabisekileyo, ziphucule ngakumbi ukuguquguquka kwazo kunye nexabiso lezoqoqosho.Ubunakho kunye nokubaluleka kwe-GVL kulindeleke ukuba ikhule kwiminyaka ezayo njengoko amashishini aqhubeka efuna izisombululo ezizinzileyo.
