A method for preparing ethoxylated <15>trihydroxymethyl propane triacrylate, including the following steps: (1) The same as the existing atmospheric esterification method, the main material is ethoxylated <15>trihydroxymethyl propane and acrylic acid are placed in the esterification reaction vessel, and toluene is added according to 50 90% of the total mass percentage of ethoxylated <15>trihydroxymethyl propane and acrylic acid, and toluene is added according to 1% of the total mass percentage of ethoxylated <15>trihydroxymethyl propane and acrylic acid. 2 4.Then add p-toluenesulfonic acid and ethoxylate <15> trihydroxymethyl propane and acrylic acid according to 0.5% of the total mass percentage of ethoxylated <15> trihydroxymethyl propane. 3 0. 5% phenothiazine was added and stirred for 29 hours, and the esterification reaction was carried out to obtain the reaction material；
Frequently Asked Questions
What is Trimethylolpropane ethoxylate?
Trimethylolpropane ethoxylate, also known as TMPEO or TMP ethoxylate, is a chemical compound that belongs to the family of ethoxylated alcohols. It is derived from trimethylolpropane, which is a triol compound used primarily in the production of polyurethanes, synthetic lubricants, and coatings.
The ethoxylation process involves the reaction of trimethylolpropane with ethylene oxide, resulting in the addition of ethylene oxide molecules to the molecular structure. This process produces a product with improved solubility, emulsifying properties, and surfactant characteristics.
Trimethylolpropane ethoxylate finds application in various industries, including:
1. Coatings and paints: It is used as a coalescing agent, which helps in the formation of a uniform film during the drying process. It also improves the durability and flexibility of the coatings.
2. Adhesives and sealants: TMPEO enhances the adhesion and cohesion properties of adhesives and sealants, allowing them to bond effectively to different surfaces.
3. Textile and leather industry: It is utilized as a textile softener and as an ingredient in leather finishing agents to improve the softness, flexibility, and water repellency of fabrics and leather products.
4. Cleaning and personal care products: TMP ethoxylate is employed as a surfactant and emulsifier in various cleaning formulations, such as household cleaners, industrial degreasers, and personal care products like shampoos and liquid soaps.
