With the increasing of the concentration of alkali, the content of insolubility of the product reduces initially but increases later, the DS of product increases initially then reduces later. The product has good solubility and high DS at 10% content of alkali. The insoluble product reduces at initially and then keeps stability later with the time of basification extending. With the increasing of the content of water in system, theinsolubility of the product reduces initially and then increases later.
