Electric Literature of 1121-89-7, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1121-89-7, name is Piperidine-2,6-dione. In an article，Which mentioned a new discovery about 1121-89-7
In the reported experiments, poly(acrylic acid) and poly(methacrylic acid) homopolymers, copolymers, and 1- mu -thick films have been converted in high yield to their corresponding cyclic imide derivatives by an in situ gas-solid phase reaction at 200 degree C with ammonia, methylamine, and ethylamine, respectively. Under similar reaction conditions with H//2S or CH//3SH as the reactive gas, sulfur was incorporated into the polymers in low yield. Under UV and electron beam irradiation, these cyclic derivatives degraded with main chain scission to eliminate isocyanic acid or alkyl isocyanate and to form olefins and ketenes. Poly(diacrylimide) was the exception and crosslinked. The poor solubility in organic solvents and the very high solubility in aqueous solutions of base limited the use of these films as positive resists. However, poly(methyl methacrylate) copolymers, containing 20%-25% cyclic groups, exhibited adequate solubility and sensitivity to be utilized as lithographic resists.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.1121-89-7. In my other articles, you can also check out more blogs about 1121-89-7
