zirconium chloride
1.The catalytic synthesis of cyclohexanone ethylene ketal with p -toluene sulfonic acid, ferric chloride, tin bichloride, tin chloride, copper sulfate, ferric sulfate, ammonium ferric sulfate, cerium sulfate, zirconium chloride, sodium bisulfate, resin, resin supported Lewis acid, molecular sieve, solid super acid, niobic acid and so on were reviewed.
2.Some new technological measures,such as new reactors,gel method to remove silicon,direct dissolve acid to recrystallizate and direct calcine from zirconyl chloride,were used to reform zirconium dioxide production process.As a result,the materials consumption and energy consumption were reduced and the wastewater discharge was decreased.Meanwhile the rubbish were recovered and utilized to prepare into a by-product as silica aerosol.The pollution prevention and control in production process were achieved.
