实验步骤: Dimethyl 2,6-naphthalenedicarboxylate and dimethyl adipate were dispersed in ethylene glycol and an addition product of two ethylene oxides to bisphenol A (BPA•2EO). Then, 0.029 part of manganese acetate tetrahydrate, 0.028 parts of antimony trioxide and 0.1% of spherical silica particles having a mean particle size of 0.3 μm were added to 100 parts of the total of dimethyl 2,6-naphthalenedicarboxylate and dimethyl adipate, and heated with stirring to conduct the reaction. The temperature was elevated to 235° C. while removing methanol produced as a by-product. After the by-production of methanol was completed, 0.03 part of trimethyl phosphate was added thereto. Then, the pressure was reduced to 0.3 Torr while elevating the temperature to 285° C. to conduct the polymerization by changing the reaction time. Dyes described in JP-A-7-168309, compounds I-6 and I-24, were each further added to the solid matter in an amount of 54 ppm. The copolymerization composition ratios of adipic acid (AA) and BPA•2EO and the intrinsic viscosities of polyesters thus obtained are shown in Table I-1. heated the reaction was elevated to 235° C. while removing methanol produced as a by-product to 285° C. the polymerization each further added to the solid matter in an amount of 54 ppm

实验步骤: Adipic acid, obtainable as product of the oxidation of cyclohexanol/cyclohexanone by means of nitric acid, having a content of 4 ppm of nitrogen is esterified by means of an acidic ion exchanger as catalyst (Amberlite IR 120) and methanol to form dimethyl adipate. After complete esterification and removal of the ion exchanger and excess methanol, the ester is distilled (18 mbar, boiling point: 115° C.) and obtained in a purity of 99.98%. The nitrogen (N) content of the ester was 4 ppm. The dimethyl adipate is hydrogenated in the gas phase at 60 bar and 195-210° C. over a copper-comprising catalyst. The space velocity over the catalyst is 0.15 kg of ester feed/liter of catalyst per hour. The reactor is a shaft reactor preceded by a vaporizer in which the feed stream is vaporized at about 195° C. with the aid of a stream of hydrogen gas. The stream of hydrogen gas is composed of fresh gas (4.5 mol/mol of dimethyl adipate) and a recycle gas stream (about 80 mol of hydrogen/mol of feed stream). Downstream of the reactor, the gaseous mixture is cooled and liquid products are taken off. The gaseous output is recirculated by means of a recycle gas compressor. A small part of the gas stream is discharged as offgas. The dimethyl adipate conversion is about 99.9%. A little methanol was lost via the offgas stream. The collected outputs (about 30% by weight of methanol, about 68% by weight of 1,6-hexanediol, about 0.5% by weight of methyl 6-hydroxycaproate and 0.06% by weight of hexanediol ester of 6-hydroxycaproic acid, about 0.3% by weight of hexanol, 0.1% by weight of dimethyl adipate, balance in each case below 0.1% by weight) have an N content of 5 ppm and are worked up by distillation. Here, predominantly methanol is removed at temperatures at the bottom of up to 140° C. and pressures of from 1013 mbar absolute to 100 mbar over a period of one hour. The remaining bottoms (about 0.08% by weight of 1,6-hexanediol methyl adipate, 0.02% by weight of the di-1,6-hexanediol ester of adipic acid, 0.3% by weight of the 1,6-hexanediol ester of 6-hydroxycaproic acid) is fractionally distilled batchwise in a distillation column (1 m packed column, reflux ratio 5, no entry of air) at 100 mbar absolute and temperatures at the bottom of about 185° C. over a period of two hours. After removal of low boilers such as residual methanol and hexanol, 1,6-hexanediol is obtained in a distillation yield of about 90% with a purity of 99.9% and an N content of 1 ppm. The N content in the remaining bottom is 15 ppm.

实验步骤: According to a process described in J. Org. Chem. 24, 261 (1959), methyl esters of carboxylic acid are obtained by the reaction of carboxylic acids with methanol in the presence of acetone dimethyl acetal, the dimethyl acetal acting as a hydrophilic agent and supplier of methanol. If adipic acid, methanol and acetone dimethyl acetal are reacted in a molar ratio of 4:5:8, a 94% yield of dimethyladipate is obtained. The economy of this procedure is impaired by the fact that the use of acetone dimethyl acetal increases the raw material costs, and the formation of acetone during the course of the reaction increases the amount of distillation required.
