Yintoni iAvobenzone Cas 70356-09-1?

Kukho iintlobo ezininzi ze-ultraviolet absorbers, phakathi kwazo i-phenylketone ultraviolet absorbers zisetyenziswa ngokubanzi kwaye zinexabiso elikhulu lophando olusebenzayo. I-Avobenzone luhlobo lwe-benzone ultraviolet efunxayo, kwaye ikwabaluleke kakhulu kwi-organic synthesis intermediate.

Isicelo

I-Avobenzone yi-sunthetic ultraviolet absorber, eyi-UV-A elungileyo (> 320nm) i-ultraviolet absorber. Inokuthintela i-UVA kwi-wavelength epheleleyo (320-400nm). Sisihluzo esisebenzayo se-UVA esine-oyile esinyibilikayo esibanzi. Inokubonelela ngalo lonke ukhuseleko lwe-UVA kunye ne-UVB xa idityaniswe nezinye iiarhente ze-UVB zokukhusela ilanga ukuthintela umhlaza wolusu obangelwa kukukhanya.
