Object of the invention are novel thermolatent bases and their use as catalysts for the preparation of polyurethanes or epoxy resins as well as a process for the preparation of polyurethanes or epoxy resins in the presence of the catalyst according to the present invention.
o-, m- and p-alkyloxybenzohydroxamic acids were synthesized and subjected to the examination for antibacterial and antifungal activity. All the hydroxamic acids tested were almost ineffective for pathogens examined of Enterobacteriaceae, but some of alkyloxybenzo- and fatty acyl-hydroxamic acid were found to be as highly effective for pathogenic fungi as butyl p-hydroxybenzoate being used as a comparison. The increase of carbon number of p-alkyloxybenzo- and fatty acyl-hydroxamic acid led to the increase in their antifungal activity, reached to the maximum at C6 in alkyloxy moiety and C10 in fatty acyl derivatives, and then the gradual decrease in both series. Considering the inhibitory power of hydroxamic acid on plant and bacterial urease, we discussed the possible correlation between antimicrobial activity and inhibitory powers on urease activity of the compounds.

Disclosed are novel processes for the production of cyclic imide compounds such as N-hydroxyphthalimide (NHPI). The processes may be particularly well-suited for commercial-scale production of cyclic imides such as NHPI. Such cyclic imide compounds are suitable for use as oxidation catalysts, and specifically may be used to oxidize cyclohexylbenzene to cyclohexyl-1-phenyl-1-hydroperoxide. Such an oxidation may be particularly useful in a process for the production of phenol and/or cyclohexanone from benzene via a process comprising hydroalkylation of benzene to cyclohexylbenzene, oxidation of the cyclohexylbenzene to cyclohexyl-1-phenyl-1-hydroperoxide, and cleavage of the cyclohexyl-1-phenyl-1-hydroperoxide to phenol and cyclohexanone. The cyclic imide production process may advantageously include water washing and reactant recovery steps to maximize purity and yield.
