Abstract: PCT No. PCT/GB90/00501 Sec. 371 Date Jul. 18, 1991 Sec. 102(e) Date Jul. 18, 1991 PCT Filed Apr. 4, 1990 PCT Pub. No. WO90/12002 PCT Pub. Date Oct. 18, 1990.A potassium salt useful in the production of certain N-substituted alkyl or arylalkyl thionitroethenamines is produced by the reaction of the dipotassium salt of a 2-nitrodithio aliphatic acid such as 2-nitrodithio acetic acid with branched chain primary alkylamines, secondary alkylamines, arylalkylamines or heterocyclic alkylamines such as dimethylamine, pinacolylamine, benzylamine or piperonylamine, thereby converting one only of the KS-groups to an alkylamine group. The resulting monopotassium salt may be alkylated or arylalkylated to produce an N-substituted alkyl or arylalkyl thionitroethenamine. This compound may be reacted with a suitable amine to produce compounds containing the pharmaceutically active grouping -NHC(=CHNO2)NHX, wherein X represents an alkyl, arylalkyl or heterocyclic alkyl group.

Title: Agglomerate production
IPC: B09B3/00
Filed: 1995-07-22
Abstract: A chemically bonded medium is obtained from a resilient organic macromolecular material, in cut elongate of finely divided form (such as grass or peat). The material is dried (3, 4) under conditions permitting escape of water vapour, such that the dried material has a predominantly hydrophobic surface and a water content of not more than 10 % by weight; and then optionally flashed. The surface properties of the dried material are then equilibrated, under conditions inhibiting escape of water vapour and other volatiles, such that the predominantly hydrophobic surface is rendered predominantly hydrophilic. The product is then mixed (5) with a lignosulfonate, with application of heat in an amount sufficient to maintain the lignosulfonate in fluid form, such that the lignosulfonate forms a coating film on the surface. The lignosulfonate is caused to undergo partial polymerisation (6) (typically by heating and/or treatment with oxygen) on the surface of the dried material to produce a flowable, substantially non-resilient and non-tacky, chemically bonded medium. The bonded medium may be stored or shaped (8) under pressure to form agglomerates.
