ORGANOSULFURS
When an end-product needs a new twist, try modifying your basic molecular structure with an active sulfur-bearing center. Reacting with an organosulfur may give you the degree of biological or pharmacological activity, the special detergency, or one of many other special characteristics you may be seeking. You'll find a wide variety of structures and properties to choose from in Pennsalt's extensive line of organosulfur building blocks. They range from thiophene and the lower alkyl mercaptans to the longer-chain mercaptans — C12 and beyond —which are more oil-soluble, less water-soluble and less volatile than short-chain ones. And Pennsalt Technical Service will help you take advantage of these versatile compounds.
You'll get aid in planning your process, selecting the most economical organosulfur, setting up handling and storage facilities, determining the most convenient and economical purchasing schedule. This table summarizes the physical properties of t h e Pennsalt organosulfurs most commonly supplied. For additional copies, write for Bulletin S-166. We also welcome your inquiries about organosulfurs not listed here. Industrial Chemicals Division, P E N N S A L T CHEMICALS CORPORATION, Three Penn Center, Philadelphia 2, Pa.
