Methacrolein, lossis methacrylaldehyde, yog aldehyde tsis txaus. Methacrolein yog ib ntawm ob yam khoom loj uas tshwm sim los ntawm cov tshuaj isoprene nrog OH hauv huab cua, lwm yam khoom yog Methyl vinyl ketone (MVK, tseem hu ua butenone). Cov sib xyaw no yog cov khoom siv tseem ceeb ntawm cov tshuaj tiv thaiv huab cua hauv huab cua ntawm cov tshuaj lom biogenic, uas tuaj yeem ua rau tsim cov ozone thiab/lossis cov khoom me me.

Nws yog tam sim no hauv cov pa luam yeeb.Kev lag luam, thawj qhov siv methacrolein yog tsim cov polymers thiab cov khoom siv hluavtaws.Qhov raug rau methacrolein yog khaus heev rau lub qhov muag, qhov ntswg, caj pas thiab lub ntsws.Qhov tseem ceeb roj ntawm tsob ntoo Loj Sagebrush (Artemisia) tridentata) muaj 5% methacrolein.

Ib qho aldehyde tsis txaus siv hauv kev tsim cov polymers thiab cov khoom siv hluavtaws. Kev tshawb fawb mob qog noj ntshav qhia pom kev noj haus thiab tso tawm cov khoom sib xyaw organic hloov pauv no hauv tib neeg cov kab mob qog noj ntshav hauv lub ntsws me me, ua rau muaj mob qog noj ntshav biomarker. Methacrolein tau siv los kawm txog qhov cuam tshuam ntawm ib feem ntawm ib billion theem ntawm cov khoom limonene oxidation thiab cov khoom lag luam terpene oxidation, methacrolein ntawm tib neeg qhov muag ntsais muag ntau zaus. Nws kuj tseem siv rau hauv kev txiav txim siab tus nqi tsis tu ncua thiab cov khoom lag luam ntawm kev cuam tshuam ntawm atomic chlorine thiab acrolein, methacrolein thiab methyl vinyl ketone.

Cov khoom lag luam nyob rau hauv patent tau muab rau R& D lub hom phiaj nkaus xwb. Txawm li cas los xij, lub luag haujlwm zaum kawg tshwj xeeb tshaj yog nrog tus neeg yuav khoom.
