Novel benzophenone derivatives and methods of making and using the same are disclosed. The novel compounds can display highly active photoinitiation and photopolymerization properties.

Aminobenzophenones and photopolymerizable compositions including the same

Novel thioxanthone derivatives and mixtures thereof and methods of making and using the same are disclosed. The novel thioxanthone derivatives can be liquid at room temperature and display highly active photoinitiation and photopolymerization properties.

Liquid thioxanthone photoinitiators

Processes for preparing aromatic carboxylic acids. Cinnamaldehyde is hydrogenated to produce a mixture of hydrogenation products, namely, hydrocinnamaldehyde and hydrocinnamic alcohol. The mixture is then oxidized using a suitable oxidizing agent to substantially completely convert both hydrocinnamaldehyde and hydrocinnamic alcohol to hydrocinnamic acid.

Processes for preparing hydrocinnamic acid

A process for preparing thioxanthone and derivatives thereof is disclosed. In the process, an aromatic compound, such as cumene, is reacted with thiosalicylic acid (TSA) or dithiosalicylic acid (DTSA) in the presence of sulfuric acid. The reaction mixture, which includes thioxanthone or a derivative thereof, is thereafter distilled under reduced pressure to recover the thioxanthone compound.
