Tom ntej: 2,2-Dihydroxy-4,4-dimethoxybenzophenone CAS 131-54-4

2,2-Dihydroxy-4,4-dimethoxybenzophenone yog dav siv los ua photoinitiator thiab UV absorber hauv polymer, txheej, thiab tshuaj pleev ib ce industries. Nws yog feem ntau muab tso rau hauv cov yas, coatings, varnishes, thiab adhesives los tiv thaiv cov ntaub ntawv los ntawm UV-induced degradation, discoloration, thiab poob ntawm txhua yam khoom. Lub compound tseem yog siv rau hauv cov tshuaj pleev thaiv hnub, cov khoom siv tu tus kheej, thiab kev siv tshuaj pleev ib ce vim nws muaj peev xwm nqus tau thiab dissipate teeb meem ultraviolet teeb. Tsis tas li ntawd, nws ua haujlwm hauv nruab nrab hauv cov organic synthesis thiab cov ntaub ntawv tshawb fawb, qhov twg nws pawg hydroxyl thiab methoxy tso cai rau kev ua haujlwm ntxiv thiab kev txhim kho ntawm UV-ruaj khov derivatives.

Cov txiaj ntsig ntawm 2,2-Dihydroxy-4,4-dimethoxybenzophenone suav nrog nws qhov muaj zog UV nqus, tshuaj lom neeg ruaj khov, thiab kev sib raug zoo nrog ntau hom polymers thiab cov qauv tsim. Nws pab pawg hydroxyl pab kom hydrogen bonding thiab koom ua ke rau hauv polymer matrices, txhim kho photostability thiab tsis kam rau thermal lossis oxidative degradation. Cov tshuaj methoxy hloov tau txhim kho cov dej hauv cov kuab tshuaj organic thiab pab tsim cov txheej txheem rau hauv cov txheej, yas, lossis cov khoom siv tshuaj pleev ib ce. Nws ruaj khov nyob rau hauv cov txheej txheem khaws cia thiab ua cov txheej txheem ua kom muaj txiaj ntsig ntev, ua rau nws muaj kev ntseeg siab ntxiv rau kev tiv thaiv cov ntaub ntawv thiab cov qauv tsim los ntawm UV puas.
