Industrial Photo Chemistry

Photochemistry is the branch of chemistry concerned with the chemical effects of light. For the industrial chemist, photochemistry is just one of the many means of producing chemical compounds or bringing them into reaction. However, it has some advantages over thermal, catalytic and other methods that immediately fascinate him. These include:
(1) Selective activation of individual reactants,
(2) Specific reactivity of electronically excited molecules,
(3) Low thermal load on the reaction system,
The main aim of preparative photochemistry is to reduce manufacturing costs for chemical products by introducing photochemical steps in the syntheses. Light-sensitive compounds have great technical significance in photography, reprography, and printing. Important applications have been also found in U.K.-curable paints, primers, and printing inks (4) exact control of radiation in terms of space, time and energy. Photo stabilizers are primarily used in plastics and man-made fibers. A Primary photochemical process of great theoretical and practical significance is luminescence. Photochemistry is an essential tool in both the manufacturing and the use of modern cars. Radiation curing is used as a very efficient, economically and ecologically attractive technology for the coating and bonding of many of the parts used in a car, and avoiding degradation of the coating due to photo induced processes during the foreseen service time is a key issue.
