The improved reverse system (MAK system) of desalting sugar liquid with ion exchange resin has reported in our previous paper. The purpose of this investigation was to determine the head loss with each ion exchange resin layer which was scheduled to use MAK process, by using a experimental apparatus, in order to draw up the industrial plan. On the basis of these experimental data, empirical formula for calculating the head loss in each resin was determined. One might conclude that the head loss with strong basic anion exchange resin layer in M or A tower, was not troublesome. Since the functions of all comercial weakly acidic cation exchange resins (K tower), have not proved consistently successful in both physical (head loss) and chemical properties (Na+ leak), it was thought advisable to investigate the excellent synthetic method of weakly acidic cation exchange resin for applying MAK process sartisfactorily. An excellent method was required for the preparation of good quality resin having high capacity, and high ion exchange rate. Having been done the development of this high quality resin which was manufactured by the Mitsubishi chemical industries Co., Ltd., in collaboration with us, the head loss problem is now settled in MAK process.
