2-Methylbenzophenone Ndi CAS 131-58-8
2-Methylbenzophenone ndi mankhwala a benzophenone, omwe ndi mankhwala abwino kwambiri.Nthawi yomweyo, matupi a ketoni ndizomwe zimapangidwira mamolekyu ambiri achilengedwe, monga zida zogwirira ntchito, zonunkhira ndi mamolekyu amankhwala.Ma ketoni onunkhira ndizofunikira kwambiri zomangira zomangira mu kaphatikizidwe ka organic, zomwe zimapezeka kwambiri m'mapangidwe achilengedwe achilengedwe ndipo zimagwiritsidwa ntchito kwambiri muzachilengedwe.
