Embodiment 1
[0028] Commodity tung oleic acid (purchased from Anhui Ruifand Oil Deep Processing Co., Ltd., model: T160) was used, cotton oleic acid was used as dispersant, and tert-butyl hydroquinone was used as polymerization inhibitor.
[0029] Take 100g of dispersant and 0.5g of polymerization inhibitor, put it in a 250mL four-necked flask, stir at 300rpm, purge with nitrogen for 30min, heat up to 220°C, add 100g of eleuic acid, react for 4h, stop heating, cool in ice water to room temperature, The dimer acid product is obtained. As determined by GPC, the content of dimer acid was 62.68%, and the content of trimer acid was 9.18%.
Embodiment 2
[0031] Commodity tung oleic acid (purchased from Anhui Reifend Oil Deep Processing Co., Ltd., model: T155) was used, cotton oleic acid was used as dispersant, and tert-butyl hydroquinone was used as polymerization inhibitor.
[0032] Take 100g of dispersant and 0.5g of polymerization inhibitor, put them in a 250mL four-necked flask, stir while purging with nitrogen, stir at a rate of 300rpm, purge with nitrogen for 30min, heat up to 220°C, add 100g of eleostearic acid, react for 4h, stop heating, Cooling to room temperature in ice water gave the dimer acid product. As determined by GPC, the content of dimer acid was 63.86%, and the content of trimer acid was 8.26%.
Embodiment 3
[0034] The same eleostearic acid, dispersant and polymerization inhibitor as in Example 1 were used.
[0035]Take 50g of dispersant and 1g of polymerization inhibitor, put them in a 250mL four-necked flask, stir while purging with nitrogen, stir at a rate of 200rpm, purge with nitrogen for 25min, heat up to 200°C, add 100g of eleostearic acid, react for 3h, stop heating, ice Cooling in water to room temperature yields the dimer acid product. As determined by GPC, the content of dimer acid was 61.80%, and the content of trimer acid was 9.28%.
