manufacture example 1～3
[0109] The succinimide compounds A to C of the first aspect of the present invention are produced. Among them, JASCO Co., Ltd. FT / IR-4100 was used for the measurement of IR spectrum. A sample that was solid at room temperature was heated and melted, and a small amount was applied to a KBr plate for measurement. For a sample that was liquid at room temperature, A small amount was directly applied to a KBr plate for measurement.
manufacture example 1
[0111] The succinimide compound A in the form of R = octadecenyl and n = 2 in the above general formula (1) was produced according to the following procedure.
[0112] Into a 200 mL four-necked flask equipped with a Dean-Stark apparatus, 57.1 mmol (20 g) of octadecenyl succinic anhydride (manufactured by Tokyo Chemical Industry Co., Ltd.), 2-aminoethanol (manufactured by Tokyo Chemical Industry Co., Ltd.) After 68.5 mmol (4.2 g) and 60 mL of o-xylene, the interior was replaced with nitrogen. Heat and stir to reflux the xylene, and discharge the generated water out of the system. After refluxing for 3 hours, the pressure was reduced while flowing a small amount of nitrogen to remove o-xylene and unreacted amine. The completion of the reaction was confirmed by IR spectroscopy. About 23 g of the target compound were obtained. exist figure 1 The middle represents the IR spectrum (Neat) of the product.
manufacture example 2
[0114] The succinimide compound B in the form of R=2,4,6,8,10-pentamethyltridecenyl and n=2 in the general formula (1) was produced according to the following procedure.
[0115] The reaction was carried out in the same manner as in Production Example 1 except that the octadecenyl succinic anhydride in Production Example 1 was changed to isoctadecenyl succinic anhydride (manufactured by Tokyo Chemical Industry Co., Ltd.), to obtain about 23 g of the target compound.
