  • STABLE SOLUTIONS OF 1,2-BENZISOTHIAZOLIN-3-ONE
    Publication number: 20160021884
    Abstract: A composition comprises 5-15 wt % of the potassium salt of 1,2-benzisothiazolin-3-one (K-BIT) calculated as 1,2-benzisothiazolin-3-one (BIT), 2-12 wt % of a nonionic surfactant, and at least 70 wt %. The presence of the nonionic surfactant stabilizes an aqueous solution of the composition at a temperature of ?5° C. A method of stabilizing an aqueous solution comprising 5-15 wt % of the potassium salt of 1,2-benzisothiazolin-3-one (K-BIT) calculated as 1,2-benzisothiazolin-3-one (BIT) and at least 70 wt % water at a temperature of ?5° C., includes the step of incorporating within the aqueous solution an amount of the nonionic surfactant so that the aqueous solution has 2-12 wt % of the nonionic surfactant.

  • Process for preparing 1,2-benzoisothiazolin-3-ones
    Patent number: 9067899
    Abstract: Sodium sulfide hydrate is at least partially dehydrated by heating with N-methyl 2-pyrrolidone. 2-Chlorobenzamide is added to the mixture which is heated further. The mixture is cooled and treated with aqueous hydrogen peroxide to give the sodium salt of 1,2-benzisothiazolin-3-one in good yield. Acidification if desired gives rise to the free 1,2-benzisothiazolin-3-one.
    Type: Grant
    Filed: April 23, 2013
    Date of Patent: June 30, 2015
    Assignee: TITAN CHEMICALS LIMITED
