Beside the uses outlined above, dimethyl sulfide is also well suited to these functions: • Solvent in extraction • Solvent vehicle • Odorant o r masking agent The staff of the Chemical Products Division offers its research facilities to explore applications of specific in­ terest t o you. Please send coupon for sample and tech­ nical information brochure. Also available: limited quantities of dimethyl sulfone and dimethyl disulfide for experimental purposes.

Which of these reactions suits your needs? Now for the first time, large quantities of low-cost 9 9 + c 7 ; pure dimethyl sulfide are available to industry— in tank cars; in 55-gallon drums; or i n 5-gallon cans. This important industrial chemical is a simple organic liquid derived by Crown Zelierbach from lignin and sul­ fur under exclusive patent rights. By integrating production of dimethyl sulfide with its vast kraft pulping process, Crown Zelierbach can now make large volumes of this low-cost chemical available for applications heretofore considered uneconomical.
