Specification:

 Tri-p-tolyl phosphite , its cas register number is 620-42-8. It also can be called Tris(4-methylphenyl) phosphite ; Phosphorous acid, tris(4-methylphenyl) ester ; and Phosphorous acid, tri-p-tolyl ester (8CI) . It is hazardous, so the first aid measures and others should be known. Such as: When on the skin: first, should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly, get medical aid. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon.
