Ukusetyenziswa

I-Homosalate, ekwabizwa ngokuba yi-protomembranous dispersion ester, luhlobo oluqhelekileyo lwesalicylic acid efunxa i-ultraviolet.Igama layo lekhemikhali yi-3,3,5-trimethylcyclohexyl salicylate, ekwazi ukufunxa i-UVB295 ～ 31Chemicalbook 5nm ukukhanya kwe-ultraviolet.Ivunyiwe yi-US FDA, iYurophu, iJapan kunye ne-Australia ukuba isetyenziswe njengemichiza yelanga ukukhusela ulusu kumonakalo wemitha ye-UVB.Isetyenziswa kakhulu kwi-sunscreen, toner kunye nezinye izithambiso kunye neengubo zempahla

Ukupakishwa kunye nokuThunyelwa

25KG/igubu

I-Homosalate yeyempahla eqhelekileyo kwaye inokuthuthwa ngolwandle okanye ngomoya

gcina kunye nokugcinwa

Ukunyaniseka: iminyaka emi-2

Gcina kwisitya esivaliweyo kwiqondo lokushisa kwaye uhlale umile

Umthamo

10 MT ngenyanga, ngoku sandisa umgca wethu wemveliso.

imiba efuna ingqalelo

I-Homosalate yi-agent ye-UVB ye-sunscreen ye-UVB, eye-arhente ye-sunscreen yekhemikhali kwaye inokufunxa iibhendi ze-UVB 295-315.Nangona kunjalo, ezinye izifundo zibonise ukuba i-Homosalate inefuthe elibuthathaka kwiihomoni kwaye ivelisa i-metabolites enetyhefu.Isixa esifunekayo asiyi kudlula kwi-10%.

ukulungiselela

Yongeza i-10.0g ye-methyl salicylate kunye ne-14.0g ye-3,3,5-trimethylcyclohexanol kwi-250ml ibhotile enentamo ezintathu, xuba kakuhle, yongeza i-5.0g ye-potassium carbonate, ukushisa ukuya kwi-120-130 ℃, uphendule nge-Chemicalbook ye-10h, kunye izinga lokuguqulwa kwe-methyl salicylate ebekwe esweni yi-chromatography yegesi yi-85.6%.Nge-vacuum distillation, i-12.2g ye-fumaric ester engenambala kunye ne-transparent ester yafunyanwa ngesivuno se-70.8% kunye nococeko lweGC olungaphezu kwe-99%.
