Abstract: A sampling system for an optical cell containing a process fluid comprises a first bi-directional pump in fluid communication with a sampling path and a second bi-directional pump in fluid communication with the first bi-directional pump and a storage vessel. The first bi-directional pump is configured to withdraw a first sample of the process fluid and to cause the first sample to flow towards the first bi-directional pump. The second bi-directional pump is configured to withdraw a second sample from the storage vessel and to cause the second sample to move toward and mix with the first sample. A first rate of withdraw of the first sample is greater than a second rate of movement of the second sample toward the first sample, and the difference between the first rate and the second rate correspond to a pre-determined ratio of the first sample mixed with the second sample.

Abstract: A method for the manufacture of a sulfonated phenol for use as a cumene hydroperoxide decomposition catalyst can comprise: combining phenol and a sulfonating agent at a first temperature that is 1° C. to 15° C. higher than a melting temperature of the phenol, to form a reaction mixture at the first temperature; reducing the first temperature of the reaction mixture to a second temperature that is 10 to 40° C. lower than the first temperature; and forming the sulfonated phenol at the second temperature.

Abstract: Systems and methods for the production of phenol and acetone from cumene oxidation products. One method includes reacting cumene and an oxidizing agent to produce a cumene oxidation product including cumene hydroperoxide and dimethyl benzyl alcohol, converting at least a portion of the dimethyl benzyl alcohol to cumene hydroperoxide by reacting the at least a portion of the dimethyl benzyl alcohol with hydrogen peroxide in both an organic phase and an aqueous to produce a converted cumene oxidation product, and cleaving the converted cumene oxidation product to produce an output product including one or more of phenol, acetone, and alpha-methylstyrene.

Abstract: The disclosure concerns methods comprising forming a phenol and acetone mixture from decomposition of a cumene hydroperoxide or a phenol, acetone, and AMS from the decomposition of a mixture containing dicumyl peroxide in a system comprising one or more reactors where at least a portion of an inner surface of the one or more reactors has a polymer coating and wherein the coating inhibits build-up of a fouling precipitate on the coated inner surface of the one or more reactors as compared to such build-up in the absence of the coating.

Abstract: A method of producing phenol and acetone can include: alkylating benzene with a C2-6 alkyl source in the presence of a zeolite catalyst to produce a C8-12 alkylbenzene; oxidizing the C8-12 alkylbenzene in the presence of an oxygen containing gas to produce a C8-12 alkylbenzene hydroperoxide; cleaving decomposing the C8-12 alkylbenzene hydroperoxide in the presence of an acid catalyst to produce phenol, a C3-6 ketone, and undesirable side products such as, but not limited to acetaldehyde, DMBA, acetophenone, AMS, AMS dimers, unidentified heavies, or a combination including at least one of the foregoing; and monitoring a concentration of the C8-12 alkylbenzene hydroperoxide in a process stream of a reactor in real time at a temperature and a pressure of the process stream; and in real time, controlling a parameter of the reactor and/or the cleaving decomposing in response to the concentration of the C8-12 alkylbenzene hydroperoxide.
