| titleOfInvention | Improved Decomposition of Cumene Hydroperoxide |
| abstract | Cumene hydroperoxide phenol by acidic catalyst, comprising decomposing cumene hydroperoxide (CHP) by non-isothermal debris in the presence of excess acetone having a molar ratio of acetone and phenol in the decomposition reactor in the range of about 1.1: 1 to 1.5: 1; Improved way to break down into acetone.n n n A process for improving the decomposition selectivity of dicumyl peroxide to α-methylstyrene in the presence of an acidic catalyst comprising carrying out a decomposition reaction at a temperature of about 80 to 110 ° C.n n n A decomposition method comprising decomposing dicumyl peroxide using an acidic catalyst system in the presence of a reaction product of (1) an amine with an acidic substance capable of catalyzing a (2) CHP decomposition reaction.n n n A composition comprising CHP, cumene, acidic catalyst for decomposition of CHP, dicumyl peroxide, dimethylbenzine alcohol, phenol and acetone, wherein the molar ratio of acetone to phenol is from about 1.1: 1 to 1.6: 1.n n n A composition comprising cumene, an acidic catalyst for CHP decomposition, DCP, water, phenol, acetone, and a reaction product of (1) amines with an acid catalyzing (2) CHP decomposition reactions.n n n (a) cracking CHP at a specific acidic catalyst concentration and temperature to form a composition comprising phenol, acetone and dicumyl peroxide, and (b) a catalyst medium that is slightly acidic than the catalyst concentration and temperature in step (a) and Moving the dicumyl peroxide to a plug flow reactor that decomposes the dicumyl peroxide into phenol, acetone and AMS at high temperature, to decompose CHP using an acidic catalyst to produce phenol and acetone.n n n Compared to the plug flow design and the CHP cracking reactor, the reactor is smaller in size (ΔT ° C, which is the difference between the inlet and outlet temperature of the plug flow reactor, is about 4 to 16 ° C) and passes part of the effluent stream of the last continuous reactor. A method of maintaining control of an acid catalyzed CHP composition in a plurality of continuous reactors comprising.n n n A process for improving CHP decomposition products comprising recycling CHP decomposition products to the CHP feed stream in an amount of about 10 to 25 times the weight of the CHP feed stream.n n n An improved process for decomposing CHP into phenols and acetone, including the presence of an additional amount of water in the CHP cracking reactor.n n n CHP decomposition products having a molar ratio of acetone to phenol of about 1.1: 1 to 1.5: 1. |
