General Description

2,2'-(P-Tolyldiyl)bis(1-phenylethan-1-one), also known as PTPTB, is a chemical compound with the molecular formula C29H24N2O. It is a yellow to orange powder with a molecular weight of 412.51 g/mol. PTPTB is primarily used as a photoinitiator in the production of UV-cured inks, adhesives, and coatings. It is also used as a stabilizer and crosslinking agent in polymers. PTPTB is known to have low toxicity and is considered to have low risk to human health and the environment. However, prolonged or repeated exposure to PTPTB may cause skin irritation or allergic reactions in some individuals.

Ultrasound-mediated synthesis of N,N-bis(phenacyl)aniline under solvent-free conditions

An efficient method for the synthesis of N,N-bis(phenacyl)anilines was developed via smooth condensation of anilines with α-bromoacetophenones in the presence of sodium carbonate as acid acceptor and polyethylene glycol 400 (PEG 400) as catalyst at room t
