- preparing a raw material mixture by mixing a dicarboxylic acid and a mono alcohol having 4 to 10 carbon atoms (S1); And a step (S2) of obtaining a product mixture including a diester-based material and product water by reacting the raw material mixture under a catalyst, wherein at least one of the following conditions A to C is applied.
- the distinction between the initial stage of the reaction and the late stage of the reaction is provided based on the reaction control point, which is a time point selected from the time point when the conversion rate of the reaction is 10% to 80%.
- the conditions A to C are as follows.
- Condition A The reactor temperature at the beginning of the reaction is set to 150 to 220°C, and the reactor temperature at the end of the reaction is set to 180 to 250°C, but the latter temperature is set to be higher than the initial temperature,

- Condition C 10 to 50% by volume was added at the beginning of the reaction and 50 to 90% by volume at the late stage of the reaction based on the total input amount of the inert gas.
- the manufacturing method begins with preparing a raw material mixture, and the raw material mixture includes a dicarboxylic acid and a monoalcohol having 4 to 10 carbon atoms, and in some cases, the dicarboxylic acid and monoalcohol One type of alcohol may be used, but a mixture of two or more types may be used.
- the raw material mixture is preferably introduced into the reactor as uniformly mixed as possible through mixing before being introduced into the reactor, rather than being directly introduced into the reactor in which the reaction is performed. It is not excluded that dicarboxylic acid and monoalcohol are directly added to the reactor as a raw material mixture, but when premixed and introduced in the form of a raw material mixture, in particular, the raw material mixture is preheated, but the reaction is carried out with sufficient preheating through the use of waste heat. It can be done easily.
- the reaction catalyst is generally separated and introduced into the reactor. In this case, by contacting the raw material mixture after preheating the reaction catalyst, side reactions that occur when the temperature is raised from the beginning with the catalyst can be prevented.
- the dicarboxylic acid contained in the raw material mixture is, for example, isophthalic acid, terephthalic acid, succinic acid, adipic acid, cyclohexane 1,2-dicarboxylic acid, cyclohexane 1,3-dicarboxylic acid, and cyclohexane 1 It may include one or more selected from the group consisting of, 4-dicarboxylic acid.
- the mono alcohol may have 4 to 10 carbon atoms, preferably 5 to 9 carbon atoms, and more preferably 6 to 9 carbon atoms.

Mixtures of structural isomers can also be used to prepare diester-based materials as compositions.
- a raw material mixture is prepared and esterified under specific conditions to obtain a diester-based material and product water.
- the esterification reaction may be, more specifically, adding a catalyst to a raw material mixture, which is a mixture of dicarboxylic acid and mono alcohol, and reacting in a nitrogen atmosphere.
- a specific point in time is designated as a reaction control point, and conditions A to C are applied by dividing the initial and late reactions based on the reaction control point, and the reaction control point is the reaction control point.
- the conversion rate is selected at a time point between 10% and 80%, and the range of conversion rates that can be selected as the reaction control point may be preferably 15%, more preferably 20%, even more preferably 25% as the lower limit, and as the upper limit. It may be preferably 75%, more preferably 70%, and even more preferably 60%.
- the reaction control point When the reaction control point is selected at a time point lower than the conversion rate of 10%, the energy consumption may increase even though the improvement of the reaction rate is not large, so it is not significantly different from the case where the condition is not applied, and is less than the time point at which the conversion rate is 80%. Selecting a reaction control point after further reaction proceeds rather becomes a factor deteriorating the reaction rate, and the meaning of changing the reaction conditions may be faded.
- reaction control point within the above range, and the initial reaction means until the reaction control point has passed, and the reaction late "" may mean a conversion rate after the reaction control point has passed.

- Condition B 40 to 90% by weight was added at the beginning of the reaction, and 10 to 60% by weight was added at the late stage of the reaction, based on the total amount of monoalcohol added, and
- Condition C 10 to 50% by volume was added at the beginning of the reaction and 50 to 90% by volume at the late stage of the reaction based on the total input amount of the inert gas.
- condition A may be a setting value of the reactor, and the conditions B and C may be to control the input amount.
- the manufacturing method is carried out in a reactor
- the reactor is a material that is vaporized by being connected to the top of the reactor, a stripper for gas-liquid separation of unreacted mono alcohol and product water, and a condenser for condensing and separating the gas discharged from the stripper.
- the reaction of step S2 may be carried out in such a reaction unit.
- the reaction temperature is higher than the boiling point of the mono alcohol and vaporization occurs, and water (product water) is formed as a reaction by-product together with the diester-based material. As they are generated, vaporization occurs together.
- the esterification reaction is an equilibrium reaction, and the product water, which is a product, must be continuously removed, and the vaporized unreacted monoalcohol must be returned to the reactor so that the reaction can proceed smoothly.
- the mixed gas of product water and unreacted mono alcohol is separated through a stripper, a condenser, and a decanter, and the mono alcohol is recycled back to the reactor, and the product water can be discharged out of the system or used as process water in the process.
- condition A among the controlled conditions is to change the temperature value of the reactor.
- the reaction is performed by setting the set value of the reactor temperature within the range of 150 to 220°C, and then changing the temperature setting of the reactor to a temperature of 180 to 250°C when the reaction control point passes.
- the reactor temperature at the end of the reaction is set to be higher than that at the beginning of the reaction.
- the set temperature of the reactor is not necessarily the same as the reactant inside it, and even if the temperature of the reactor is set to 200°C, the reactant may be a process of raising the temperature toward 200°C, and it may be the same temperature as it has already been raised, and some heat loss However, it may be a lower value due to reflux or the like.
- the temperature of the reactor is initially controlled between 150 and 220°C, the initial reflux of monoalcohol can be suppressed and unnecessary heat loss can be prevented. If the temperature is set to a temperature lower than 150°C, the reaction rate is too slow and The side reaction rate is high, and if the temperature is set higher than 220°C, unnecessary heat loss may occur and the reaction product may suffer heat damage, whereas the reaction rate cannot be improved due to the rapid increase in the reflux amount of alcohol, so setting an appropriate level of temperature may be essential. have.
- the temperature must be raised to an appropriate level in order to maximize the reaction conversion rate. In this case, it is necessary to set it to a value between 180 and 250°C. If the temperature is set to a temperature lower than 180°C, the conversion rate cannot be achieved up to 99%, so the purity of the product cannot be met. If the temperature is set to a temperature higher than 250°C, the possibility of thermal damage to the product increases. Alternatively, the possibility of generating scale due to the catalyst is high, and further, due to an increase in the amount of reflux at the end of the reaction, the time required for the conversion rate to exceed 99% may be lengthened or may not be achieved.
- the set value of the reactor temperature at the initial stage of the reaction is selected from 150 to 220°C, and the reaction late is changed to a value between 180 to 250°C. It may be effective in preventing problems in advance and achieving energy consumption improvement, and preferably, the reactor temperature at the beginning of the reaction may be set to 160 to 190°C, and the reactor temperature at the end of the reaction may be set to 200 to 250°C.
- condition B is a divided dose of alcohol.
- the amount of alcohol added to the reactor or mixer at the beginning of the reaction is 40 to 90% by weight based on the total amount, and 10 to 60% by weight, which is the remainder of the amount added at the beginning of the reaction, from the total amount in the late reaction after the reaction control point.
- alcohol can be added in a batch based on the reaction control point, at the beginning of the reaction, continuous injection over the entire time point, or divided within the initial amount of the reaction.
- the same method can be applied, and the input method can be applied independently for each of the initial and late reactions.
- the alcohol may be used in the range of 150 to 500 mol%, 200 to 400 mol%, 200 to 350 mol%, 250 to 400 mol%, or 270 to 330 mol% based on 100 mol% of dicarboxylic acid. . With the amount selected within the above range as 100% by weight, 40 to 90% by weight may be added at the beginning of the reaction, and the remainder may be added at the late stage of the reaction.
- the reaction rate may not be improved at all, and only the energy consumption may be increased.
- the reaction does not proceed predominantly and water is not removed due to an increase in the amount of monoalcohol making azeotrope with the remaining water, deactivation of the catalyst or a situation with a dominant reverse reaction may occur during the reaction, so the reaction speed is slow and energy consumption Can grow.
- the amount of alcohol to be added at the beginning of the reaction is set to 40 to 90% by weight based on the total input amount, and at the end of the reaction, the balance of the total input amount is set to 10 to 60% by weight.
- This can be effective in reducing energy consumption and improving reaction speed.
- the amount of the diester-based material and the amount of the total amount of 100% added from the initial stage are controlled. Reactivity can be expected to be improved by improving the reaction contact area of the mono alcohol.
- the amount of alcohol to be added at the beginning of the reaction is set to 40 to 80% by weight based on the total input amount, and at the end of the reaction, it is set to 20 to 60% by weight. It can be, more preferably 40 to 70% by weight at the beginning of the reaction, it may be set to add 30 to 60% by weight at the late stage of the reaction.
- condition C among the controlled conditions is the divided injection amount of the inert gas.
- the inert gas introduced into the reactor during the initial reaction is 10 to 50 vol% of the total input amount, and the inert gas input at the end of the reaction, that is, after the reaction control point, is 50 to 90 vol%, which is the balance excluding the initial input amount from the total input amount.
- the inert gas is introduced based on the reaction control point, by batch injection into the reactor filled with reactants at the start of the reaction, continuous injection over the entire time point, or separate injection within the initial input amount of the reaction.
- the same method can be applied to the reaction late stage, and the input method can be applied independently to each of the initial and late reaction stages.
- the inert gas may be one or more selected from the group consisting of nitrogen, argon, and helium, and this plays a role of controlling the amount of reflux for discharging the product water, and the entire amount is injected from the beginning or 50 volumes of the total input amount before reaching the reaction control point. If it is added in excess of %, the problem of energy consumption may occur due to an increase in the reflux amount, and if it is less than 10% by weight, it is difficult to discharge the product and thus a problem of reaction delay may occur. Accordingly, when the inert gas input amount is controlled within the above range, reactivity and productivity can be improved, preferably 10 to 40 vol% of the total input amount is added at the beginning of the reaction, and 60 to 90 vol% are added at the end of the reaction. can do.
