Abstract: A process for producing an essential oil. The essential oil can be white mustard essential oil. The white mustard essential oil can include a moisture sensitive isothiocyanate compound. The moisture sensitive isothiocyanate compound can be 4-HBITC. The essential oil can be produced from mustard seed, which can comprise a precursor sinalbin and myrosinase enzyme. The mustard seed can be reduced into a powder. Activation of the myrosinase enzyme by using a water solvent and a promoter to form a slurry can be performed, wherein the myrosinase enzyme catalyzes the production of an essential oil comprising an isothiocyanate from the sinalbin precursor.

Abstract: Polymers and copolymers synthesized by means that yield a narrow range of molecular weights can have different properties than polymers synthesized by conventional means. In order to obtain such polymers, however, polymerization must be controlled. One type of controlled polymerization is the reversible addition-fragmentation chain transfer (RAFT) process, which has characteristics of a living polymerization. The present invention discloses a group of dithioesters and trithioesters suitable as chain transfer agents for RAFT polymerization. The present invention also discloses RAFT polymerizations conducted in aqueous media.
