Abstract: A vertical reactor system having a plurality of substantially vertically aligned reaction compartments one on top of the other, the reactant materials (and catalyst and solvent, if desired), flowable from a first top compartment through intermediate compartments, if any, to a bottom compartment from which a desired product of a reaction of the reactant materials is withdrawn, the compartments having inlets for the addition of additional reactants, catalysts, or solvents and outlets for withdrawing by-products, vapors, and water from any compartment, and processes for producing products using such a system. In one embodiment the product is a liquid epoxy resin. Stirring impellers may be provided in any compartment. A liquid seal may be provided on a shaft for the impellers and, in one embodiment the seals in each compartment may be elevated above the liquid in the compartments.

Abstract: Disclosed is an apparatus and process for producing a tripropylene glycol in which alkylene oxide, water, an acid catalyst and a dipropylene glycol are contacted together under conditions suitable to form the tripropylene glycol. Water is present in the reaction mixture in the range of about 1 to about 50 weight percent of the reaction mixture. The ratio of water to alkylene oxide is less than about 9. The tripropylene glycol thus produced exhibits a higher primary hydroxyl group content generally exceeding 36 percent. Such tripropylene glycols find utility in the production of acrylics. Also disclosed is a process for making esters from such glycols.

Abstract: An improved process for preparing a silver catalyst which comprises impregnating a porous alumina support with a silver salt, preferably silver nitrate, by contacting a quantity of the support with an aqueous solution of the salt in sufficient amount to be completely absorbed by said support while under a vacuum. A dispersing agent is also employed in the aqueous silver salt solution. The support is dried by heating, e.g. 100.degree. C., under vacuum and then, while still under vacuum, impregnated with a reducing agent employing an amount sufficient to be completely absorbed by the support. Subsequent heating at a higher temperature, e.g. 250.degree. C., reduces the silver salt to silver metal. A catalyst is produced which, when employed for the oxidation of ethylene, permits the process to run 5.degree.-10.degree. C. cooler at the normal conversion and also gives an improved yield.

Abstract translation: 一种改进的制备银催化剂的方法，其包括用一种银盐，优选硝酸银浸渍多孔氧化铝载体，通过使一定量的载体与该盐的水溶液充分接触，以使其完全被所述载体吸收，同时在下 一个真空。 在银盐水溶液中也使用分散剂。 载体通过加热干燥，例如 100℃，然后在仍然在真空下，用还原剂浸渍，其量足以被载体完全吸收。 随后在较高温度下加热，例如 250℃，将银盐还原成银金属。 产生一种催化剂，当用于乙烯的氧化时，催化剂允许该方法在正常转化时冷却至5〜10℃，并且还提高了产率。
