  • Process for the manufacture of granular monohydrated sodium perborate
    Patent number: 4942025
    Abstract: Process for the manufacture of granular monohydrated sodium perborate, endowed with abrasion resistance, starting from the corresponding tetrahydrated perborate, characterized in that a carboxylic acid, containing from 1 to 3 C atoms, or an alkali metal salt thereof, is added to the tetrahydrated perborate, already present in the granular state, whereafter a dehydration of the tetrahydrated perborate is carried out.
    Type: Grant
    Filed: November 3, 1989
    Date of Patent: July 17, 1990
    Assignee: Ausimont S.p.A.

  • Process for the production of granular sodium perborate monohydrate having good mechanical strength
    Patent number: 4894211
    Abstract: The invention relates to a process for the production of granular sodium perborate monohydrate having good mechanical strength. The process is characterized in that sodium silicate having an SiO.sub.2 /Na.sub.2 O molar ratio comprised within the range of from 0.4 to 2.0 is added to granular sodium perborate tetrahydrate while this is being kept in movement and the so processed perborate tetrahydrate is dried until perborate monohydrate is obtained.

  • Water-soluble trisazosulfonated dyestuff derived from 2-aminophenol-4-sulfonic acid, resorcinol, 4,4'-diaminobenzanilide and m-aminophenol
    Patent number: 4052375
    Abstract: A water-soluble triazo dyestuff of the formula: ##STR1## The dyestuff, which is useful in dyeing cotton and other cellulosic fibers, is prepared by diazotizing 2-aminophenol-4-sulfonic acid, coupling the diazotized sulfonic acid with resorcinol, treating the reaction mixture with a copper complexing agent at 35.degree.-40.degree. C and a pH of 5-5.5, separately tetraazotizing 4,4'-diaminobenzanilide, coupling the tetraazotate with the previously formed reaction product to form a diazo-disazoic reaction product, and coupling the latter product with m-aminophenol to produce the desired dyestuff.
