Examples
Embodiment 1
[0027] In a 250mL three-necked flask equipped with a stirring, thermometer and constant pressure dropping funnel, add 40g cashew nut shell liquid, 30mL dichloromethane, and 5g triethylamine, dissolve 2mL disulfide dichloride in 15mL dichloromethane and then Add dropwise through a constant-pressure dropping funnel, control the reaction temperature to 0°C, and the dropping rate to be about 1 drop / sec. The tail gas is absorbed with dilute lye. After the addition, the reaction is continued for 1 hour, and 5 mL of distilled water is added to terminate the reaction. The system was extracted with petroleum ether / distilled water, and the obtained oil phase was subjected to a rotary evaporator to remove the solvent, and a reddish-brown oily liquid was obtained, named Y-1. The yield was 95%.
Embodiment 2
[0029] In a 250mL three-necked flask equipped with stirring, thermometer and constant pressure dropping funnel, add 40g cardanol, dissolve 1mL disulfide dichloride in 15mL dichloromethane and then add dropwise through constant pressure dropping funnel to control the reaction temperature When the temperature is 0°C, the dropping rate is about 1 drop / sec. The tail gas is absorbed with dilute lye. After the dropping is completed, the reaction is continued for 1 hour, and 5 mL of distilled water is added to terminate the reaction. The system was extracted with petroleum ether / distilled water, and the obtained oil phase was subjected to a rotary evaporator to remove the solvent, and a reddish brown oily liquid was obtained, named Y-2. The yield was 96%.
Embodiment 3
[0031] In a 1000 mL three-necked flask equipped with a stirring, thermometer and constant pressure dropping funnel, add 200 g cashew nut shell liquid and 200 g cardanol, dissolve 10 mL of disulfide dichloride in 100 mL dichloromethane and then drop through the constant pressure dropping funnel. Add, control the reaction temperature to 0°C, the dropping rate is about 1 drop / sec, the tail gas is absorbed with dilute lye, after the dropping is completed, the reaction is continued for 1 hour, and 5 mL of distilled water is added to terminate the reaction. The system was extracted with petroleum ether / distilled water, and the obtained oil phase was subjected to a rotary evaporator to remove the solvent to obtain a reddish brown oily liquid named Y-3. The yield was 97%.
