Phosphorus-containing additives such as sodium tripolyphosphate have excellent properties as detergent assistant, and they had been widely used in the detergent industry. The research for replacing these phosphorus-containing assistant has been paid much more attentions during the last three decades because the over-nutrition in the water is more and more serious. 4A zeolite is an ideal non-phosphorus detergent assistant. By employing bauxite as raw material, the detergent assistant 4A zeolite is synthesized, the synthetic cost is decreased. Under hydrothermal synthetic conditions, the quality of product is increased by introducing amorphous crystallization director, and the total reaction time is shortened from 5~7 h to 80 min. The optimal synthetic conditions are determined by investigating the effects of conversion of bauxite, the amount of crystallization director added, gel formation time and temperature on the calcium ion exchange performance. Thus, the 4A zeolite product with high crystallization granularity and excellent calcium exchangeability is obtained. The main index of the product reaches or exceeds the trade standard. The production cost of this 4A zeolite as detergent assistant is much more decreased, and it will promote the non-phosphorus course of detergent in domestic market.

Phosphorus-containing additive such as sodium tripolyphosphate has been widely used in the detergent industry for its excellent properties as detergent assistant. The research on replacing phosphorus-containing assistant has been paid great attention during the last three decades due to its over-nutrition in related water body. The layered sodium silicate, a new phosphate-free detergent assistant, can be produced with soluble glass as raw material by being spray-dehydrated and calcined. The temperature of spray-dehydration and calcination was optimized. The crystalline end product with high crystallization at 450 ℃ of spray-dehydration and at 800 ℃ of calcination for 1 hour was verified by X-ray diffractometry. It is concluded that the layered sodium silicate with calcium exchangeability of 343 mg (CaCO 3)/g and less calc water of 2.38% is a preferable detergent assistant for phosphate-free detergent.
