Magnesium Silicate

Synthetic Magnesium Silicate Adorbent is refered as synthetic, amorphous form of magnesium silicate, it is safe, pure fine white compound with porous internal structure and enormous activated surface, products are ideal for use as adsorbents, anti-static flow agents, anti-caking agents, catalyst supports, carriers, and reinforcing fillers, it get rid of chemical with polarity as your want.

Magnesium Silicate adsorbs a wide ragne of polar compounds
Our first production line of Synthesis Magnesium Silicate Adsorbent was put into use in 1994, we sold this adsorbent as special/fine chemical to polyols makers. When producing polyether polyols using an alkaline catalyst these catalysts are preferably removed from the polyol at the end of production by a proper finishing step, synthesis magnesium silicate could be used for purifying the crude polyols, it could remove the catalysts, and make the color looks more transparent but not the yellowish crude one. our magnesium silicate was designed for that purpose primarily. in a lot of patented production process of purifying the polyesters, polyols and polymers, magnesium silicate is often introduced and is certificated as useful adsorbent. MACROSORB MP5 and MP5 PLUS

Our second production line was successful lanuched in 2003 to have an additional capacity of 1,500mts per annum when it is discovered that magnesium silicate adsorbs a wide range of impurities like glycerin, free glycerin, metals, soaps, chlorophyll, residual free fatty acids, odors, color, methanol and water from 1) * Treament of Used/Fried Cooking Oil ; 2) Treatment of Biodiesel Fuel. 3purifying of non-polar organic compound  

Treatment of cooking oil and free fatty acid with Magnesium Silicate

 Used as adsorbent for when purifying of non-polar organic compound typically like polyether polyols, it has been discovered that the process of catalyst removal from polyols can be improved by adding a critical amount of water, 1.0 to 5.0 percent by weight, based on the weight of polyol to the mixture of polyol and adsorbent prior to heating and filtration.
