Participants

Reaction Steps

75 ml of Fraction 2 which contains 4.8 g of pantothenate were brought to a pH of 7, with stirring, by adding solid calcium hydroxide. The resultant calcium D-pantothenate solution or suspension was then dried by evaporating off water on a rotary evaporator and 8.98 g of a light-brown calcium D-pantothenate powder were obtained which has a content of 57% calcium D-pantothenate. This powder has no tendency to stick together and has good product properties.
