摘要在各种脂肪族和环状烯烃的均相氧化过程中,研究了二氧钼(VI)和二氧铀(VI)均双金属双-ONO三齿(2-羟基-1-亚苄基)丙二酰,琥珀酰和对苯二di配合物的催化势。使用H 2 O 2水溶液或TBHP(叔丁基过氧化氢)作为末端氧化剂。催化潜力是定量的,并且具有很高的选择性,可提供相应的氧化物产物与Mo VI O 2络合物,比使用H 2 O 2水溶液的U VI O 2络合物高5倍。或TBHP。在含水H 2 O 2的Mo VI O 2配合物催化的1,2-环辛烯的氧化中,研究了各种溶剂和温度的影响,结果发现,最合适的溶剂是乙腈,最适温度为70°C。初步描述和讨论了机理途径。 图形概要

It is an object of the present invention to provide a novel imidazole alcohol compound that adheres strongly to metal surfaces in metal products, especially copper, aluminum and steel products, and that has a superior rust-preventive effect even in a thin film, and a surface-treating agent using the same. The novel imidazole alcohol compound is expressed by the following general formula (1) show a rust-preventive effect.

The present invention is to provide a low solvent content type-coating composition by which the resultant coatings with good scuff resistance or water resistance as well as good chipping resistance are produced, while the content of an organic solvent to be used can be much reduced. The low solvent content type-coating composition comprises a polyester oligomer having a hydroxyl group in an amount of 2.0 to 10.0 moles/Kg-resin, a number average molecular weight (Mn) of 300 to 1500, a weight average molecular weight (Mw) of 300 to 3000, and a ratio of a weight average molecular weight/a number average molecular weight (Mw/Mn) of 1 to 2.0, an amount of a modifying lactone being 31 to 85%, and an aliphatic hydrocarbon group of C4-22 which is not derived from lactones. The present invention is also to provide a process for coating a low solvent content type-coating composition on, for example, a base coating composition by a wet-on-wet coating. The base coating composition comprises a vinyl oligomer having a hydroxyl group and/or a blocked hydroxyl group, a melamine resin containing 50 to 100% of an imino type or methylol type mononucleus melamine and a weak acidic curing catalyst.
