Abstract: 2,2'-(Thiobis(nitromethylidyne))bis(tetrahydro-2H-1,3-thiazine), useful as an insecticide.

Abstract: Lubricant additives imparting oxidation inhibiting properties to lubricant compositions, are synthesized by reacting thioxamide, saturated aliphatic aldehyde of from 1 to about 20 carbon atoms, and an olefin of at least 8 carbon atoms, in the presence of a boron trifluoride catalyst.

Abstract: Methine dyes from tetrahydroquinoline compounds containing N-thioether substituents, in general produce bright yellow shades when applied to polyester fabrics by conventional dyeing procedures, have improved properties such as dyeability, fastness to light, resistance to sublimation, insensitivity to pH changes, and dye at the boil and under pressure to the same depth of shade. These compounds are particularly useful in the thermal fixation technique for dyeing polyester materials.
