Introduction 1,1, 1-tris (hydroxymethyl) ethane is an organic intermediate, can be used for the preparation of anionic surfactant three, the product has good water solubility, wettability, foaming and foam stability.
Product characteristics trimethylolethane (TME) is a special multi-functional polyol with three highly reactive hydroxyl groups of the new pentane structure. The neopentane structure provides excellent stability, improved resistance to heat, light, hydrolysis, and oxidation; And outstanding weatherability, gloss, and chemical resistance.
trimethylolethane trimethylolethane (TME) is a high-performance polyol with three primary hydroxyl groups, odorless, free-flowing, white crystalline solid. The polybasic acid may be reacted to form a polyester resin. These polyester resins with hydroxyl groups can be cross-linked and cured with isocyanate, Amino Resin, etc., or modified with silicone resin, epoxy resin and other resins, for high temperature resistance, oxidation resistance, weather resistance, products with high light retention requirements. It can also be used in the fields of polyester synthetic lubricating oil, plasticizer, plastic stabilizer and titanium dioxide coating, so that the product has good weather resistance, light resistance and temperature resistance.
The compact neopentyl structure of trimethylolethane (TME) provides a high content of hydroxyl groups with excellent resistance to heat, light, hydrolysis and oxidation. TME can be used as a polyol for the synthesis of alkyd resin, TME alkyd resin can be manufactured with high quality color and excellent weather resistance, thermal stability, light retention, baking resistance and stain resistance of coatings and other products.
TME typical application areas are:
1 external coatings such as automotive coatings, electrical coatings, agricultural machinery coatings, and marine coatings, industrial coatings, wood and anti-corrosion coatings to meet the requirements of high weather resistance areas;
2 high temperature (greater than 200 ℃) baking ceramic non-stick pan coatings, such as high weather resistance and good thermal resistance of modified silicone polyester coatings;
3 Hydrolysis-resistant and acid-resistant beverage coatings;
4 heat-curing ink, which has good gloss, hardness, solubility-resistance and thermal stability;
5 artificial lubricants, to meet the oxidation and corrosion stability testing requirements;
6 alkyd resin reactive diluent.
TME can also be used for surface treatment of other solid heat storage solar energy materials and other inorganic pigments such as titanium dioxide.
application field trimethylolethane is mainly used in polyester, polyurethane, alkyd resin, epoxy resin, high solid resin, the production of reducible resin, powder coating resin and silicone modified resin; Also used in the production of lubricants, inks, plasticizers, special explosives; Also used as a coating agent for titanium dioxide and so on.
Development prospects at present, there are few reports on the research of three sub-surfactants at home and abroad, attract a lot of researchers to continue to do more research.
Use organic intermediates.
