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.

Thiol ester compositions and processes for making and using same

A method for removing conjugated olefins from a composition comprising contacting the composition with a Diels-Alder dienophile to convert conjugated olefins to a Diels-Alder adduct and arresting the Diels-Alder adduct. A method comprising confining a Diels-Alder dienophile to a first side of a selectively permeable barrier wherein the barrier is more permeable to conjugated olefins and less permeable to Diels-Alder dienophile and Diels-Alder adduct, and contacting a composition comprising mono-olefins and conjugated olefins with the Diels-Alder dienophile to form Diels-Alder adduct, wherein the contacting reduces the concentration of conjugated olefins in the composition. A method for removing conjugated olefins from a composition comprising bubbling the composition through a liquid comprising Diels-Alder dienophile to form a liquid comprising Diels-Alder adduct. A method for removing conjugated olefins from a non-solid composition comprising contacting the composition with a solid comprising Diels-Alder dienophile to form a solid comprising Diels-Alder adduct.

Process for the removal of conjugated olefins from a monoolefin stream

A process for the separation of conjugated olefins from monoolefins in a fluid comprising such conjugated olefins and monoolefins using a Diels-Alder reaction to provide a fluid comprising a Diels-Alder adduct and monoolefins. The fluid comprising such Diels-Alder adduct and monoolefins can be subjected to a separating means to thereby recover a resulting monoolefin-containing fluid containing less than about 50 parts per million conjugated olefins. The process is particularly useful for purification of fluids containing normal alpha olefins.
