Mixtures of sodium salts of phthalic and chlorophthalic acids containing sodium chloride

Mixtures of sodium salts of phthalic and chlorophthalic acids containing sodium chloride. Rejlek, Antonin; Kroupa, Jaroslav (Czech. ). Czech. CS 212686 B 15 Oct 1984,4 pp. (Czech).Chemical with cas number 56047-23-5 also plays role.Chemical with cas number 56047-23-5 also plays role. (Czechoslovakia). CODEN: CZXXA9. CLASS: IC: C07C063-20. ICA: C07C063-68; C09B047-04. APPLICATION: CS 80-1627 10 Mar 1980. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Crude mixts. contg. 40-75% mono-Na 4-chlorophthalate [56047-23-5], 4-6% mono-Na 3-chlorophthalate [68966-32-5], 12-40% Na H phthalate [827-27-0], 6-36% Na phthalate [15968-01-1], 8-29% NaCl, and the balance dichlorophthalates are used in the synthesis of stabilized phthalocyanine pigments. They are prepd. by gradually treating an aq. suspension of phthalic anhydride [85-44-9] at 60° with a predetd. amt. of an aq. NaOCl soln., adjusting the pH to 3.7 with HCl or H2SO4, cooling, sepg. the pptd. product, and drying in a fluidized bed. ..
