Methods for synthesizing a mercaptan compound include the steps of contacting a nickel-molybdenum catalyst with HS at a sulfiding temperature of less than or equal to 235° C. to form a supported sulfur-containing catalyst, and then contacting an alcohol compound or an olefin compound, HS, and the supported sulfur-containing catalyst to form a reaction mixture containing the mercaptan compound.

Methods of making mercaptan compounds using nickel-molybdenum catalysts

The present invention discloses high pressure flow reactor vessels and associated systems. Also disclosed are processes for producing thiol compounds and sulfide compounds utilizing these flow reactor vessels.

Flow reactor vessels and reactor systems

Thiol ester compositions, methods of making the thiol ester compositions, and methods of using the thiol ester compositions are provided. In some embodiments, the thiol ester compositions include thiol esters, hydroxy thiol esters and cross-linked thiol esters. The thiol ester composition can be used to produce cross-linked thiol esters, sulfonic acid-containing esters, sulfonate containing esters and thioacrylate containing esters. The thiol ester compositions can be used to produce polythiourethanes. The polythiourethanes can be used in fertilizers and fertilizer coatings.

Removing impurities from a heptane stream by contacting the heptane stream with an acidic catalyst, wherein the contacting reduces a concentration of one or more close boiling impurities, one or more olefins, or both. The impurities are isomerized via contact with the acidic catalyst into species that possess lower octane levels or that do not possess boiling points as near to the boiling point of n-heptane, which promotes separation of the impurities via distillation. Close boiling impurities may include such compounds as cis-1,2-dimethylcyclopentane and methylcyclohexane or may be compounds having boiling points at a standard pressure of 760 Torr in the range of about 96.5 to about 100.5 degrees Celsius including such compounds as cis-1,2-dimethylcyclopentane and methylcyclohexane. The concentration of cis-1,2-dimethylcyclopentane and methylcyclohexane may be reduced by at least about 25 and 10 percent by weight, respectively. The concentration of olefins, as measured by the Bromine Index, may be reduced by at least about 25 percent by weight.
