Abstract: PURPOSE: A method for preparing acrylic acid and acrylic ester based on lactic ester is provided to implement preparing processes by continuously dehydrating the lactic ester under a calcium phosphate catalyst. CONSTITUTION: Calcium phosphate slurry is generated by mixing apatite cake and sodium diphosphate cake with deionized water. The apatide cake is obtained by mixing and filtering a first phosphate dissolved aqueous solution and a first calcium salt dissolved aqueous solution. The sodium diphosphate cake is obtained by mixing and filtering a second phosphate dissolved aqueous solution and a second calcium salt dissolved aqueous solution. The calcium phosphate slurry is filtered, washed, dried to form calcium phosphate cake. The calcium phosphate cake is dried and ground to form powder. The powder is pelletized. The pelletized product is plasticized in the air at a temperature between 300 and 700 degrees Celsius.
