摘要:
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.
摘要:
Methods of promoting the cure of unsaturated polymer resins with a peroxide initiator by including as a promotor N-alkyl-N-(2-hydroxyalkyl)-p-toluidines. The use of the tertiary aromatic amines as a promotor provides a fast cure at a wide range of temperatures. Polymerizable compositions and methods of applying the same to a surface are also described.
