摘要： A cylinder block for multi-cylinder engine includes a cooling water passage provided at a head-side portion of a cast metal inter-bore wall. The cooling water passage includes a plurality of vertically adjoining transverse water passages provided in vertical and multiple stages. A connecting wall portion of the cooling water passage includes at least one cast metal connecting wall connecting a front wall portion of the inter-bore wall to a rear half wall portion thereby separating the vertically adjoining transverse water passages from each other. The cooling water passage has its cast metal wall surface which faces a water passage spaced exposed in its entirety as a molded surface. The cooling water passage further includes a pair of left and right rising water passages to permit cooling water flowing within a left and right cylinder jacket of the block that is introduced into the cooling water induction portions to flow into the cooling water passage and thence upwardly out of the block via the rising water passages to circulate in a head jacket located above the block. Left and right cylinder head tightening boss portions having under surfaces are provided, and cooling water induction portions are arranged in proximity to the under surfaces of the boss portions.

摘要： There is provided a noble process for producing a salicylic ester for perfumes which comprises the step of transesterifying a salicylic lower alkyl ester with an alcohol having at least one carbon atom which is located adjacent to a hydroxyl-bonded carbon atom and has one or more hydrogen atoms bonded thereto, in the presence of a tin-based catalyst. The process of the present invention enables the salicylic ester to be produced at a high yield and is free from handling problems such as precipitation of solids in a distillation residue obtained after the reaction, and the catalyst used therein is reusable.

摘要翻译： 提供了用于制备用于香料的水杨酸酯的贵重方法，其包括使水杨酸低级烷基酯与位于羟基键合的碳原子附近的至少一个碳原子的醇进行酯交换并具有一个或多个氢 在锡基催化剂存在下键合的原子。 本发明的方法能够以高产率生产水杨酸酯，并且不会在反应后获得的蒸馏残渣中处理诸如固体沉淀的问题，并且其中使用的催化剂是可重复使用的。
