  • Patent number: 5192498
    Abstract: It has now been discovered that the undesirable odor in thiocarbamate compounds can be suppressed or mostly eliminated by the process of this invention. Generally, the process of this invention involves mixing an aqueous solution of sodium hypochlorite, calcium hypochlorite or chloramine-B with the odorous thiocarbamate compound for a sufficient period of time, followed by a second step of mixing citric acid, maleic acid or oxalic acid with the treated thiocarbamate compound to eliminate chlorodialkylamine compounds produced in the first step.

  • Patent number: 5185356
    Abstract: A particulate composition comprising an isothiazolinone or isothiazolothione or a salt or complex thereof and a water soluble metal salt. The salt is typically a metal salt, for example the sodium salt of 1,2-benzisothiazolin-3-one and the water soluble metal salt is particularly an alkali metal salt such as disodium hydrogen phosphate. A preferred composition can be obtained by stirring together an isothiazolinone or isothiazolothione, a base and an alkali metal phosphate in the presence of water until a dry particulate product is obtained. The particulate product is typically highly and rapidly soluble in water and may be stored in a container formed from a water soluble material, for example a bag formed from polyvinyl alcohol.
