Embodiment 1

[0032] Take 300g of refined cardanol and put it into a high-pressure reactor, add 0.6g of 50% potassium hydroxide solution, and carry out nitrogen replacement. ℃~130℃ for dehydration. After the dehydration is completed, raise the temperature to 135°C-160°C, add 44g of ethylene oxide to carry out the epoxidation reaction, control the temperature of the addition reaction at 130°C-190°C, and control the pressure below 0.3MPa. After the addition reaction is completed, Lower the temperature to 65°C-75°C, add 0.33g of acetic acid to neutralize until the pH value reaches 5.0-8.0, and obtain cardanol polyoxyethylene ether. A certain amount of pentadecyl (en) base metaphenol (cardanol) polyoxyethylene ether, glucose 180g, solid acid TiO 2 / SO 2 -4 and TiO 2 -ZrO 2 / SO 2 -4 Put 3.44g of mixed catalyst into the reactor, stir evenly, reduce the pressure to 4kPa, rapidly raise the temperature to 90-120°C, keep the temperature for 2.5-4.0h, and continuously pump out the generated water...

Description

technical field [0001] The invention relates to the technical field of surfactants, in particular to a pentadecyl m-phenol polyoxyethylene ether-based glucoside and a preparation method and application thereof. Background technique [0002] Surfactants can change the properties of gas-liquid, liquid-liquid and liquid-solid interfaces, so that they have various performances such as foaming, defoaming, emulsification, dispersion, penetration, and solubilization. Therefore, surfactants are widely used in various fields of human activities, such as daily chemicals and cosmetics, food and feed processing, leather product processing, chemical fiber processing, textile printing and finishing, pharmaceutical processing, mineral flotation, oil exploration, oil products, etc. Processing, industrial washing and other industrial sectors, known as "the most efficient industrial monosodium glutamate". Although the amount of surfactant is small, it has a great effect. Mainly divided into...
