2-Methyl-3,4-Pentadienoic Acid Ethyl Ester(CAS#60523-21-9)
Isingeniso
I-Ethyl 2-methyl-3,4-pentadienoic acid iyinhlanganisela yezinto eziphilayo, evame ukufushaniswa njenge-MEHQ. Okulandelayo yisingeniso semvelo, ukusetshenziswa, indlela yokukhiqiza kanye nolwazi lokuphepha lwe-MEHQ:
Ikhwalithi:
- Ukubukeka: I-MEHQ iwuketshezi olungenambala oluphuzi olukhanyayo.
- Ukunyibilika: I-MEHQ iyancibilika kwezinye izinyibilikisi zemvelo njenge-ethers, utshwala nama-ketones, futhi ayincibiliki emanzini.
Sebenzisa:
- Ama-Antioxidants: I-MEHQ isetshenziswa kabanzi njenge-antioxidant emikhiqizweni yenjoloba nepulasitiki ukuze yandise isikhathi sayo sokuphila ngaphansi kwezimo eziphakeme zokushisa nezimo zemisebe ye-UV.
- Iziqinisi zokukhanya: I-MEHQ iphinde isetshenziswe kuma-sunscreens kanye nemikhiqizo yokuvikela ilanga ngenxa yezakhiwo zayo ezimelana ne-UV.
Indlela:
Indlela evamile yokulungiselela i-MEHQ iwukuba i-esterification ye-2-methyl-3,4-pentadienic acid (i-Mesaconic acid) ene-ethanol, ngokuvamile ngaphansi kwezimo ze-acidic.
Ulwazi Lokuphepha:
I-MEHQ iwushevu ongaba yingozi empilweni uma uvezwa futhi uhogelwe. Nazi izinyathelo zokuphepha:
- Gqoka okokuvikela okufanele, njengezingubo zamehlo ezivikelayo namagilavu, uma usetshenziswa.
- Sebenzisa endaweni enomoya omuhle futhi ugweme ukuhogela umhwamuko wayo.
- Gcina esitsheni esingangeni moya, kude nomlilo namazinga okushisa aphezulu.
