SHORTEST DISTANCE TO T O M O R R O W ' S BETTER L I V I N G . . . " C D " CHEMICALS These comprise really high molecular weight Amines ... Nitriles ... Ketones... Amides Acid Chlorides . . . All i n regular daily, largescale commercial p r o d u c t i o n . . . Normal alkyl chains ranging in length from 6 to 18 carbon atoms i n the saturated series . . . 9-octadecene and 9-12-octadecadiene in the unsaturated series. Fields of utility are still largely unexplored but are expanding rapidly. Your request for samples should b e as specific as possible t o avoid duplication o f effort.
