DDC-I TYPE HIGH-TEMPERATURE RESISTANT STRONG-ACID RESIN-CATALYST
( DDC-I CATALYST )
I. INTRODUCTION
Our company successfully fulfilled the industrial production of DDC-I CATALYST, replenished the domestic industrial blank and got the China national patent.
Passing the dynamic, static and active evaluation test, both of its active and heat stabilizer reached the standard of foreign equivalent type catalyst, such as B-24, etc. We already used in several METHYL ETHYL KETONE producers in domestic. It has the high ability of catalytic activity, excellent high-temperature resistant and can be work at 100-180C at long time period.
Besides these, our DDC-I CATALYST also has the character of low corrosion, no environment pollution, simple operative process, saving energy, enabling continuous production, etc. Our DDC-I CATALYST has substituted SULFURIC ACID and can be widely used in the organic reaction process of fine chemical field.
