Lub zeem muag ntawm δ-Valerolactone

Delta-valerolactone, tseem hu ua δ-Valerolactone, yog ib tug cyclic organic compound uas tau txais kev pom zoo nyob rau hauv xyoo tas los no vim nws cov tshuaj zoo heev thiab kev siv ntau yam. Nws belongs rau tsev neeg ntawm lactones thiab yog muab los ntawm 5-hydroxypentanoic acid.

Nyob rau hauv cov nqe lus ntawm nws cov khoom, δ-Valerolactone yog cov kua xim tsis muaj xim nrog ib qho tsw qab me ntsis thiab qhov kub ntawm 203 degrees Celsius. Nws yog soluble hauv ntau cov kuab tshuaj organic xws li ethanol, methanol, thiab acetone, tab sis insoluble hauv dej. Nws kuj muaj cov tshuaj toxicity tsawg thiab yog ib puag ncig tus phooj ywg, ua rau nws xav tau lwm txoj kev rau cov kuab tshuaj ib txwm muaj.

Ib qho ntawm cov kev siv tseem ceeb tshaj plaws ntawm δ-Valerolactone yog nyob rau hauv thaj chaw ntawm biofuels. Nws yog ib qho kev cog lus raw khoom rau kev tsim cov biofuels vim nws lub zog siab ceev thiab tsis muaj tshuaj lom. Nws kuj tseem tuaj yeem siv los ua cov kuab tshuaj rau lignocellulosic biomass, uas yog ib qho txuas ntxiv thiab muaj ntau lub zog.

Tsis tas li ntawd, δ-Valerolactone tau pom muaj peev xwm zoo hauv kev lag luam polymer. Nws tuaj yeem siv los ua lub tsev thaiv rau kev sib txuas ntawm ntau yam polymers, xws li polyesters thiab polyurethanes. Cov polymers no muaj cov khoom siv kho tshuab zoo heev thiab tuaj yeem siv rau ntau yam kev siv, suav nrog txheej txheej, nplaum, thiab textiles.

Lwm qhov kev zoo siab ntawm δ-Valerolactone yog nyob rau hauv cov tshuaj. Nws tau pom tias muaj cov khoom siv tshuaj tua kab mob thiab tuaj yeem siv los ua tshuaj tua kab mob. Tsis tas li ntawd, nws tau kawm txog nws lub peev xwm los ua tus neeg xa tshuaj, vim nws tuaj yeem hloov kho tau yooj yim rau lub hom phiaj tshwj xeeb lossis cov ntaub so ntswg.

Zuag qhia tag nrho, δ-Valerolactone muaj lub neej yav tom ntej nyob rau hauv ntau yam lag luam vim nws cov khoom tshwj xeeb thiab cov kev siv tau zoo. Raws li lub zej zog tseem ceeb tshaj qhov tseem ceeb ntawm cov peev txheej ruaj khov thiab txuas ntxiv mus ntxiv, δ-Valerolactone yuav tsis ntseeg tau ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li cov kev xav tau no.
