Ukusetshenziswa

I-Homosalate, eyaziwa nangokuthi i-protomembranous dispersion ester, iwuhlobo olujwayelekile lwe-salicylic acid emunca i-ultraviolet.Igama layo lamakhemikhali yi-3,3,5-trimethylcyclohexyl salicylate, ekwazi ukumunca ukukhanya kwe-UVB295 ～ 31Chemicalbook 5nm ultraviolet.Igunyazwe yi-US FDA, Europe, Japan kanye ne-Australia ukuthi isetshenziswe njengamakhemikhali okuvikela ilanga ukuvikela isikhumba emonakalweni wemisebe ye-UVB.Isetshenziswa kakhulu ekukhiqizweni kwelanga, i-toner nezinye izimonyo nezindwangu zokugqoka

Ukupakisha kanye Nokuthumela

25KG/isigubhu

I-Homosalate ingeyempahla evamile futhi ingathuthwa ngolwandle noma ngomoya

gcina nokugcina

Ukuba semthethweni: 2 iminyaka

Gcina esitsheni esivaliwe ekamelweni lokushisa futhi uhlale womile

Amandla

10 MT ngenyanga, manje sandisa umugqa wethu wokukhiqiza.

izindaba ezidinga ukunakwa

I-Homosalate i-ejenti yokuvikela ilanga ye-UVB ye-UVB, okungeyekhemikhali evikela ilanga futhi ikwazi ukumunca amabhendi e-UVB 295-315.Kodwa-ke, ezinye izifundo zibonise ukuthi iHomosalate inomphumela obuthakathaka kumahomoni futhi ikhiqiza ama-metabolites anobuthi.Inani elidingekayo akufanele lidlule u-10%.

ukulungiselela

Faka u-10.0g we-methyl salicylate kanye no-14.0g we-3,3,5-trimethylcyclohexanol ebhodleleni elingu-250ml elinezintamo ezintathu, hlanganisa kahle, engeza u-5.0g we-potassium carbonate, ukushisa kufika ku-120-130 ℃, sabela nge-Chemicalbook amahora angu-10, kanye izinga lokuguqulwa kwe-methyl salicylate eqashwe nge-gas chromatography ngu-85.6%.Nge-vacuum distillation, i-12.2g ye-fumaric ester engenambala futhi esobala itholwe ngesivuno esingu-70.8% kanye nobumsulwa be-GC obungaphezu kuka-99%.
