Trimethylolpropane Production process introduction

Trimethylolpropane referred to as TMP, is an important chemical raw materials and organic intermediates. Mainly used in the production of alkyd resins and polyurethanes, but also for the production of high-grade coatings, rosin esters, surfactants, fiber processing agents, plasticizers and advanced lubricants.

There are two main methods for the synthesis of trimethylolpropane:
 Condensation disproportionation and condensation hydrogenation.

Condensation disproportionation method is a traditional one-step synthesis method, this technology is more mature, but many by-products, Need to consume a large amount of alkali, formaldehyde consumption, high cost. This method is suitable for batch production.

Condensation hydrogenation method is developed in the 90's two-step method, First condensation and then hydrogenation, Can save one-third of formaldehyde and a large amount of alkali, relatively few by-products, Purification is more simple, less equipment, low cost. However, this method requires high hydrogenation equipment and catalysts and is suitable for continuous production.

Our company designed and manufactured 1 to 30,000 tons of trimethylolpropane complete sets of devices for Shandong Fufeng (Sweden) Perstorp Chemical Co., Ltd., Wuxi Baichuan Chemical Co., Ltd. have achieved great success.
 We can provide customers with the design, manufacture, commissioning an annual output of 1 to 30,000 tons of trimethylolpropane complete sets of equipment.
