  • Flame retardant composition and flame-retardant synthetic resin composition containing same
    Patent number: 11753527
    Abstract: In a flame retardant composition containing (poly)phosphoric acid amine salts, the amine excess ratio (mol %) represented by formula (I) is 0.01-10 mol %. In the formula, n represents the number of types of amines in the (poly)phosphoric acid amine salt, and A1-An represent the maximum number of dissociation steps of each amine. Here, the maximum number of dissociation steps is the maximum number of dissociation steps with a base dissociation constant pKb at 25° C. in the 0-13 range. B1-Bn represent the number of mol of the amine when an amine is assumed to be present alone in the (poly)phosphoric acid amine salt.
    Type: Grant

  • Method for preparing jelly foods
    Patent number: 3969536
    Abstract: A jelly food is prepared by successively1. assembling more than two materials2. heating the assembly to a temperature of not lower than 60.degree.C and3. cooling the same,Said materials containing a thermally gelable polysaccharide composed predominantly of .beta.-1,3-glycosidic groups and being prepared by holding a dispersion containing the polysaccharide at 55.degree. to 80.degree.C.
