    摘要: Glycol ether esters can be prepared by reaction of an epoxide with an ester of a carboxylic acid using an amidine catalyst. The reaction can be used, for example, to prepare methoxypropyl acetate propylene oxide and methyl acetate. By carrying the reaction out in the presence of an alcohol solvent the corresponding glycol ether is also formed.

    摘要: A process for the production of an ester comprises reacting an olefin with carbon monoxide, hydrogen and another ester at elevated temperature and pressure in the presence of a catalyst comprising (1) a rhodium source, (2) a ruthenium source, and (3) cobalt or zinc iodide. The product ester comprises the acid group of the ester used as reactant esterified with a hydrocarbyl group derived from the olefin, hydrogen and carbon monoxide.

    摘要: Formamides e.g. diethylformamide are prepared by reacting a primary or secondary amine e.g. diethylamine or ammonia with (a) an alkyl formate or (b) carbon monoxide and an alkanol in the presence, as catalyst, of (i) a compound containing an amidine group or (ii) a Group V element-containing Lewis base and an epoxide. The Lewis base can be a trivalent nitrogen or phosphorus-containing compound. The amidine group which can be cyclic or acyclic can form part of a guanidine group.

    摘要: An improved spa control system is disclosed. The invention describes a spa control system which calculates the time required to heat the water in the spa system to a desired temperature. From that information, the heating rate of the spa system can be determined, and the heating element of the spa system can be activated at the proper time to raise the temperature of the water to a selected temperature by a desired time. The spa system also monitors information which might show errors in the operation of the spa system such as a blockage in the flow of water over the heating element in the spa system.
