IR and NMR analyses confirm the structure. The extracts are then dried over anhydrous sodium sulfate, gravity filtered and concentrated on a rotary evaporator to a weight of 6. The hydrogen sulfide bubbling is continued for a period of two hours at which time it is ceased and addition of the 4-chlorononanone produced in Example I Asupra, is commenced. The reaction mass is concentrated on a rotary evaporator using water aspirator vacuum to a volume of about 3 ml and a thick slurry is obtained. The infrared spectrum is set forth in FIG. Thickener compounds include carriers, binders, protective colloids, suspending agents, emulsifiers and the like, e. An additional 0.
