YieldReaction ConditionsOperation in experiment
[0692] In the same manner as in Example II-15, 148 g (1 mole) of phthalic anhydride was reacted with 74 g (1 mole) of isobutanol with a peroxide value of 0.1 meq/kg and a carbonyl value of 0.1 as alcohol component 1, whereby the total acid number of the reaction mixture became 252 mgKOH/g (theoretical value: 252 mgKOH/g). [0693] Then, to the reaction mixture was added tin oxide (0.2 wt. percent based on the starting materials fed) as a catalyst, and at 220° C., 7.4 g (0.1 mole) of said isobutanol and 158.4 g (1.1 moles) of <strong>[3452-97-9]3,5,5-trimethylhexanol</strong> with a peroxide value of 0.1 meq/kg and a carbonyl value of 0.2 as alcohol component 2 were further added dropwise. While water generated during the reaction was removed by water separator, the esterification reaction was carried out at 220° C. for about 6 hours until the total acid number of the reaction mixture became 3 mgKOH/g or less, and further continued at 220° C. and at 20000 Pa for 1 hour. [0694] After the reaction, the excess alcohols were removed by distillation at 180° C. under a reduced pressure of 1330 Pa, and the obtained liquid residue was neutralized by adding thereto 30 g of a 4percent aqueous solution of sodium hydroxide and stirring the mixture at 80° C. for 2 hours, and then washed with water until it became neutral, giving a crude ester mixture. At this point, the crude ester mixture had a total acid number of 0.01 mgKOH/g. [0695] Subsequently, to the crude ester mixture was added activated carbon ("Shirasagi M" manufactured by Sumitomo Chemical Co., Ltd.; 0.1 wt. percent based on the starting materials fed), and the mixture was stirred at 90° C. and at 1330 Pa for 1 hour and filtered, whereby 329 g of a purified ester mixture containing (isobutyl) (3,5,5-trimethylhexyl) phthalate was obtained. Dehydration was carried out at 100° C. under a reduced pressure of 1330 Pa for 6 hours. [0696] The total acid number and kinematic viscosity of the obtained ester mixture are shown in Table 6. The ester mixture had a water content of 11 ppm, a sulfated ash content of less than 1 ppm, a sulfur content of less than 1 ppm, a phosphorus content of less than 1 ppm, a hydroxyl value of 1.4 mgKOH/g, a peroxide value of 0.2 meq/kg and a carbonyl value of 0.2. The obtained ester mixture was found to be a mixture of the following esters from the gas chromatogram thereof: [0697] (1) diisobutyl phthalate [0698] (2) (isobutyl)(3,5,5-trimethylhexyl) phthalate [0699] (3) di(3,5,5-trimethylhexyl) phthalate [0700] (1)/(2)/(3)=21.9/44.2/33.9 (area percent)
