摘要： Processes for the production of chlorinated and/or fluonnated propenes provide good product yield with advantageous impurity profiles in the crude product. Advantageously, the processes may be conducted at lower temperatures than 600° C., or less than 500° C., so that energy savings are provided, and/or at higher pressures so that high throughputs may also be realized. The use of catalysts or initiators may provide additional enhancements to conversion rates and selectivity, as may adjustments to the molar ratio of the reactants.

摘要： Phenolic glycol ethers, e.g., ethylene glycol phenyl ether, are prepared by a continuous, nonaqueous process comprising the steps of (A) contacting under isothermal reactive conditions in a first reactor or reaction zone an alkylene oxide, e.g., ethylene oxide, with (i) a stoichiometric molar excess of a phenolic compound, e.g., phenol, and (ii) a catalytic amount of a base, e.g., sodium hydroxide, homogeneously dispersed throughout the phenolic compound, to form a first intermediate phenolic glycol ether product, (Bj transferring the first intermediate phenolic glycol ether product to a second reactor or reaction zone, and (C) subjecting the first intermediate phenolic glycol ether product to adiabatic reactive conditions in the second reactor or reaction zone to form a second intermediate phenolic glycol ether product comprising phenolic glycol ether, unreacted phenolic compound, catalyst, water and byproduct glycols. In addition, the mono-/di-product weight ratio can be adjusted by increasing or decreasing the amount of base catalyst employed.
