According to the report, Wanhua Chemical's annual production of 60,000 tons of neopentyl glycol project is planned to be built in Yantai Chemical Industrial Park, Yantai Economic and Technological Development Zone, Shandong Province.
The main raw material of this project, the isobutyraldehyde consumption is 45,500 tons/year, and the formaldehyde consumption is 54,800 tons/year.
Neopentyl glycol is mainly used in the production of saturated polyester resins, unsaturated polyester resins, polyester polyols, esters used in synthetic lubricants, polymer plasticizers and alkyd resins
The neopentyl structure provides polyester products with excellent chemical stability, weather resistance, chlorine resistance, thermal stability and resistance to UV radiation
In addition, Wanhua Chemical also released a draft for comments on the environmental impact report of the Trimethylolpropane project with an annual output of 50,000 tons

Construction content and scale: a new set of trimethylolpropane production plant with an annual output of 50,000 tons, as well as supporting storage and transportation projects, public works and auxiliary facilities, environmental protection projects, etc.
, and some public auxiliary facilities and environmental protection projects of the project Relying on Wanhua Chemical's existing or under construction projects
The report shows that the raw materials of the project, n-butyraldehyde, formaldehyde and hydrogen are all self-produced in Wanhua Industrial Park and are directly supplied by pipeline.
The hydrogenation catalyst is also a self-developed catalyst, and the price and supply of the two are very reliable; station, etc.
, make full use of the three wastes and waste heat of the main device to generate steam and chilled water, realize energy integration and greatly reduce consumption; this project is jointly designed with the other two Wanhua projects to jointly build roads, pipe networks and other public works facilities, living and office facilities.
, Shared management and production personnel, can greatly reduce the cost of the three projects
.
Trimethylolpropane (hereinafter referred to as TMP) is an important fine chemical product, mainly used in alkyd resins, polyurethanes, unsaturated resins, polyester resins, coatings and other fields, and can also be used in the synthesis of aviation lubricants and printing inks etc.
, can also be used as textile auxiliaries and heat stabilizer for PVC resin; TMP is a commonly used chain extender in the resin industry (resin chain extender with a wide range of applications), and it is one of the upgraded products of the polyol industry.
It has a low melting point and has 3 methylol groups in its molecular structure, so it has polyol properties similar to glycerol.
It can not only replace glycerol to synthesize alkyd resin, but also can be used with polyols such as neopentyl glycol and pentaerythritol to produce alcohol.
acid resin
.
Alkyd resin made of TMP has better hydrolysis resistance, oxidation stability, alkali resistance and thermal stability, especially suitable for the production of road marking paint, and also used for household use such as automobiles, refrigerators and washing machines Finishing paint for electrical appliances
.
It is also used in the production of surfactants, wetting agents, explosives, plasticizers, glass fiber reinforced plastics, rosin esters, advanced aviation lubricants, fiber processing agents, printing inks and polyurethane foams.
Auxiliary and heat stabilizer for PVC resin
.
Derivatives of TMP can also be used as cross-linking agents, curing agents, emulsifiers, release agents and catalysts, and can also be used to manufacture liquid membrane electrodes with strong selectivity to sodium ions
.
In China, TMP is mainly used as a raw material for the preparation of PU curing agents, synthetic UV coatings and high-grade alkyd resins, and its consumption accounts for more than 70% of the total domestic consumption of trihydroxyl.
In addition, it can also be used in polyester resins and titanium White powder field
.
TMP is mainly used to synthesize high-grade alkyd resins and light curing agents for high-grade paints and paint inks for automobiles.
With the continuous improvement of environmental protection requirements, the demand for light curing agents is also increasing, so the corresponding demand for TMP will also increase significantly
.
With the continuous deepening of China's energy saving and emission reduction, green environmental protection economic policies and the rapid development of new material application fields, the application scope of TMP products in the field of new materials will continue to expand, and its development prospects are very broad
.
