    Abstract: In a process for producing phenol and cyclohexanone, a cleavage feed containing greater than 40 wt % and no greater than 95 wt % cyclohexyl-1-phenyl-1-hydroperoxide, and at least 5 wt % and less than 60 wt % cyclohexylbenzene is mixed with at least phenol, cyclohexanone, water, and sulfuric acid to produce a cleavage reaction mixture containing from 15 wt % to 50 wt % phenol, from 15 wt % to 50 wt % cyclohexanone, from 1 wt % to 10 wt % cyclohexyl-1-phenyl-1-hydroperoxide, from 5 wt % to 60 wt % cyclohexylbenzene, from 0.1 wt % to 4 wt % water, and from 10 wppm to 1000 wppm sulfuric acid. The cleavage reaction mixture is then reacted at a temperature from 30° C. and to 70° C., and a pressure of at least 1 atmosphere for a time sufficient to convert at least 50% of said cyclohexyl-1-phenyl-1-hydroperoxide in said cleavage reaction mixture and produce a cleavage effluent containing phenol and cyclohexanone.

    Abstract: An alkylating process such as hydroalkylating process comprising feeding a gas material and a liquid material into the reactor, distributing the liquid material to the upper surface of a bed of a catalyst substantially uniformly. The substantial uniform distribution of the liquid material to the upper surface allows for substantially uniform distribution of liquid reaction medium in the bed, thereby preventing hot spot and undesirable continuous liquid zone, both of which can cause the production of undesired by-products. The invention is particularly useful for the hydroalkylation reaction of benzene in making cyclohexylbenzene, which can be used for making cyclohexanone and phenol.

    Abstract: A continuous process for preparing an ethylene-based polyolefin, the process comprising maintaining a polymerization mixture at a temperature at or above the lower critical phase separation temperature of the polymerization mixture, while, during said step of maintaining, maintaining the polymerization mixture at steady state, where the polymerization mixture is substantially uniform in temperature, pressure, and concentration, where the polymerization mixture includes solvent, monomer including ethylene and optionally monomer copolymerizable with ethylene, a single-site catalyst system, and polymer resulting from the polymerization of the monomer, where the monomer and the polymer are dissolved in the solvent, and where the polymer is an ethylene-based polyolefin having a molecular weight distribution (Mw/Mn) of less than 2.30.

    Abstract: An elastomeric composition is disclosed. The elastomeric composition includes, per 100 parts by weight of rubber (phr): about 70 to about 90 phr of polybutadiene having a cis-1,4 linkage content of at least 95%; about 5 to 20 phr of a processing oil; about 5 to about 20 of sunflower oil; about 50 to about 75 phr of a filler; a curative agent; an antioxidant; and about 5 to about 30 phr of a propylene-ethylene-diene terpolymer containing from about 0.2 wt % to about 20 wt % ethylidene norbornene and/or vinyl norbornene and about 10 wt % to about 30 wt % of ethylene and/or C4-C20 α-olefins derived units.
