Jinyan chemical alcohol ether project was approved in August 2018, and it took 6 months from construction to production. The whole process was completed within 48 hours of commissioning test run, and the production is stable at present. The main products of this project are: methyl allyl alcohol polyoxyethylene ether, isopentenol polyoxyethylene ether, ethylene glycol monovinyl polyoxyethylene ether, diethylene glycol monovinyl polyoxyethylene ether, fatty alcohol polyoxyethylene ether, polyethylene glycol, etc., the downstream is mainly used in cement admixture industry.

At the same time, the alcohol-ether project is supported by synthetic research and development laboratory, product application laboratory, concrete performance testing laboratory, etc., which all support product research and development, optimization and technology improvement.

Jinyan chemical alcohol ether project adopts external circulation spray ethoxylation method, namely Press third generation double external circulation spray process. Compared with other process routes, gas-liquid contact area is larger and reaction speed is faster. The non-stirring rotary device also reduces the risk of EO leakage and contact. In the production process, due to the good control of the reaction process, the unreacted EO in the product is less, the side reaction is less, the molecular weight distribution of the product is narrow, and the three wastes are less. The whole production process is controlled by DCS with stable and safe operation. The project adopts a number of domestic and foreign advanced technology: single granulation technology, automatic formula of the whole process, one-button start and stop, cold and heat energy utilization, intelligent management of equipment, etc., effectively realize the upgrade and transformation from automatic factory to new intelligent factory.

At present, the alcohol-ether project has been in operation for more than half a month. Since the product was put into the market, it has won high recognition from customers for its good particle appearance, less product dust, stable index, excellent quality and excellent technical service.
