Embodiment 1
[0023] Step 1: Dissolve 15.1g of cardanol, 6.9g of potassium carbonate, 0.83g of potassium iodide, and 0.08g of tetramethylammonium chloride into 20g of N,N-dimethylformamide, and stir at room temperature for 0.5h in a nitrogen atmosphere , then be warming up to 110 ℃, dropwise add 4.63g1-chlorobutane (the mol ratio of cardanol, 1-chlorobutane, potassium carbonate, potassium iodide is 1:1:1:0.1, the quality of tetramethylammonium chloride is 0.5% of the cardanol quality), continue to react for 10h; after filtering, washing and vacuum distillation, yellow cardanol butyl ether is obtained;
[0024] Step 2: Weigh 10.8g cardanol butyl ether and 1.56g formic acid, keep the system temperature at -5~0°C, add 6.8g 30wt.% hydrogen peroxide (cardanol butyl ether, formic acid) dropwise at a rate of 10mL / h , The molar ratio of hydrogen peroxide is 1:1:2), react at this temperature for 48h. After the crude product is washed and dried, the finished epoxy cardanol butyl ether plasticizer is...
Embodiment 2
[0026] Step 1: Dissolve 15.1g of cardanol, 10.4g of potassium carbonate, 0.75g of sodium iodide, and 0.08g of benzyltriethylammonium chloride into 25g of N,N-dimethylacetamide in a nitrogen atmosphere at room temperature Under stirring for 0.5h, then warming up to 120°C, 9.3g of 1-chlorobutane (the molar ratio of cardanol, 1-chlorobutane, potassium carbonate, sodium iodide is 1:2:1.5:0.1, benzyl triethyl The quality of ammonium chloride is 0.5% of the quality of cardanol), and the reaction was continued for 8h; after filtering, washing and distillation under reduced pressure, light yellow cardanol butyl ether was obtained;
[0027] Step 2: Weigh 10.8g cardanol butyl ether, 0.78g formic acid, maintain the system temperature at 0-5°C, add 4.1g 50wt.% hydrogen peroxide (cardanol butyl ether, formic acid, hydrogen peroxide) dropwise at a rate of 20mL / h The molar ratio is 1:0.5:2), and reacted at this temperature for 36h. After the crude product is washed and dried, the finished e...
Embodiment 3
[0029] Step 1: Dissolve 15.1g of cardanol, 7.6g of potassium carbonate, 0.83g of potassium iodide, and 0.32g of tetramethylammonium chloride into 30g of N,N-dimethylformamide, and stir at room temperature for 1 hour in a nitrogen atmosphere. Then be warming up to 130 ℃, dropwise add 9.3g1-chlorobutane (the mol ratio of cardanol, 1-chlorobutane, potassium carbonate, potassium iodide is 1:2:1.1:0.1, the quality of tetramethylammonium chloride is cashew nut 2% of the phenol mass), continue to react for 6h; after filtering, washing and distillation under reduced pressure, yellow cardanol butyl ether is obtained;
[0030] Step 2: Weigh 10.8g cardanol butyl ether and 1.56g formic acid, keep the system temperature at 0-5°C, add 6.8g 30wt.% hydrogen peroxide (cardanol butyl ether, formic acid, The molar ratio of hydrogen peroxide is 1:1:2), react at this temperature for 48h. After the crude product is washed and dried, the finished epoxy cardanol butyl ether plasticizer is obtained. ...
