Embodiment 1

[0026] In a 5L autoclave equipped with a stirrer, a meter, a heating temperature control device, a cooling device (including an outer jacket and an inner coil) and a pressure sensor, add 362 g of tetrapolyglycerol, 5.5 g of potassium hydroxide, and replace with nitrogen for 5 times After adding 135g of ethylene oxide, heat up and stir, and react at 80-85°C with a pressure of 0.25MPa for 2 hours. Afterwards, the temperature was raised to 115°C, and the pressure was controlled at 0.25MPa. The remaining 2013g of ethylene oxide was divided into 10 batches and added successively. After the addition was completed, the reaction was carried out, and the post-aging was performed for 4 hours. After that, a phosphoric acid aqueous solution was added to neutralize the reaction at 100°C. For 1 hour, add 1.5g of magnesium silicate and 1.5g of aluminum silicate, stir well for 20 minutes, dehydrate and filter under vacuum, add antioxidant Chic3338: 1.5g, ChicF96: 3.0g to the obtained polyether...

Embodiment 2

[0028] In a 5L autoclave equipped with a stirrer, a meter, a heating temperature control device, a cooling device (including an outer jacket and an inner coil) and a pressure sensor, add 100 g of triglycerol, 150 g of tetraglycerol, 110 g of pentaglycerol, Potassium hydroxide 6.5g, nitrogen replacement 3 times, add 190g propylene oxide, heat up and stir, react at 80-85°C, pressure 0.2MPa for 2 hours. Afterwards, the temperature was raised to 110°C, the pressure was controlled at 0.3MPa, and the remaining 2650g of propylene oxide was divided into 8 batches and added successively. After the addition was completed, the reaction was carried out, and after aging for 5 hours, the phosphoric acid aqueous solution neutralizing agent was added to carry out the neutralization reaction at 95°C. Hours, add 3.3g of magnesium silicate and 2.3g of aluminum silicate, fully stir for 20 minutes, dehydrate and filter under vacuum, add antioxidant Chic3338: 5.0g, ChicF96: 2.5g to the obtained poly...

Embodiment 3

[0030] In a 5L autoclave equipped with a stirrer, a meter, a heating temperature control device, a cooling device (including an outer jacket and an inner coil) and a pressure sensor, add 350 g of tetraglycerol, 120 g of pentaglycerol, and 8 g of potassium hydroxide, Nitrogen was replaced 4 times, 90g of butylene oxide was added, heated and stirred, and reacted at 80-85°C and pressure 0.3MPa for 2 hours. Afterwards, the temperature was raised to 115°C, and the pressure was controlled at 0.3MPa. The remaining 1558g of propylene oxide was divided into 9 batches and added successively. After the addition was completed, the reaction was carried out, and the post-aging was performed for 6 hours. After that, a phosphoric acid aqueous solution was added to neutralize the reaction at 95°C. 1 hour, add 3g of magnesium silicate and 4.5g of aluminum silicate, stir thoroughly for 20 minutes, dehydrate and filter under vacuum, add antioxidant Chic3338: 3.0g, ChicF96: 3.0g to the obtained pol...

Abstract

The invention belongs to the technical field of chemical synthesis, and particularly relates to polyglycerol polyether polyol and a preparation method thereof. The polyglycerol polyether polyol is prepared from, by weight, 300-500 parts of initiator, 1500-3000 parts of oxyalkylene, 5-10 parts of catalyst, 8-20 parts of neutralizer, 2-8 parts of adsorbent and 10-20 parts of compound additives. According to the polyglycerol polyether polyol and the preparation method thereof, the raw materials are easy to obtain, pollution is less, the synthetic method is simple, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a polymerized glyceryl polyether polyol and a preparation method thereof. Background technique [0002] Currently commercially available polyether polyol products often use sucrose, sorbitol, propylene glycol, glycerin, etc. as initiators, among which the initiators with higher functionality are mainly sucrose, sorbitol, etc. Few products involve the use of polymerized glycerol as the main starting system. [0003] Polyglycerin has higher viscosity and boiling point than glycerin, less volatility and hygroscopicity, good moisture retention, and has the characteristics of improving emulsification stability, so it is often used in cosmetics, fiber industry, plastic industry and other fields, but as an initiator preparation There are basically no reports on polyethers. [0004] The polyether polyol product prepared by using polyglycerin as the main starting ...
