Abstract

1,216,975. Preparing optical brighteners. VYZKUMNY USTAV ORGANICKYCH SYNTEZ. 26 Feb., 1969, No. 10428/69. Heading C2C. [Also in Division C4] In Example 3, the optical brightener of the formula is reacted with manganese II chloride to form the manganese salt which is filtered off, suspended in water and converted to the soluble sodium salt by addition of sodium carbonate, manganese carbonate being precipitated and filtered off.
