Abstract

Jojoba oil (Simmondsia) has been sulfurized with sulfur monochloride and S in order to study the kinetics and parameters of the process and the characteristics of the final product. Reaction runs were conducted in the range of sulfur content 0-8%, addition time to 140 min, agitation speeds 100-500 rpm, temperature 20- 100°C, and solvent dielectric constant range 2-35. Analysis of the results was helped by tracking the reaction with NMR spectra. Reaction between the oil and S2Cl2 occurs by addition to the double bond, and cross linkage takes place with a corresponding increase in viscosity and molecular weight. Reaction in solvents follows a first-order rate with respect to the percentage of double bonds, and is highly influenced by the dielectric constant of the solvent and the addition of accelerators.
