Diisooctyl Sebacate Preparation

A reaction tool for the synthesis as well as manufacturing of Diisooctyl Sebacate. The gadget includes an esterification pot, an esterification tower, an esterification condenser, a separator, a correction kettle, a correction tower, a rectification condenser, an alcohol receiving tank, as well as an ester receiving container. Vacuuming system and pump delivery system. The outer surfaces of the esterification kettle and the rectification kettle are equipped with a thermal oil furnace for heating up the materials in the esterification kettle or the rectification pot. The thermal oil furnace is outfitted with In various other places other than the top of the esterification pot as well as correction kettle, as well as avoid the discharge port at the end of the esterification pot as well as correction kettle;

The esterification tower is organized on top of the esterification pot. The electrical outlet end of the esterification tower is attached to the inlet end of the esterification condenser. The outlet end of the esterification condenser is attached to the inlet end of the separator. On the side of the separator The wall surface is likewise provided with an alcohol recovery pipe that remains in circulation communication with the esterification pot. The discharge port of the esterification kettle is connected to the feed port of the correction kettle via a product pump in the pump delivery system. The rectification tower is supplied with At the top of the correction kettle, the outlet end of the correction tower is linked to the inlet end of the rectification condenser, and the outlet end of the rectification condenser is attached to the alcohol finding container and the ester receiving tank.

The warm transfer oil furnace is provided with a warmth transfer oil inlet as well as a heat transfer oil outlet. The warm transfer oil inlet and also warm transfer oil outlet are specifically mounted on top of one side of the outer surface area of the heat transfer oil heater as well as all-time low of the other side. The thermal oil furnace is also provided with a thermometer socket for installing a thermostat to gauge the temperature level in the esterification kettle or rectification pot. The top of the esterification pot is offered with an acid feed port, an alcohol feed port, a stimulant inlet and also a vent port.

A process for manufacturing Diisooctyl Sebacate, consisting of the adhering to actions:
Action 1. According to the molar ratio of isooctyl alcohol and also sebacic acid being 2:1, evaluate the sebacic acid for later usage, add excess isooctyl alcohol right into the esterification pot, and then begin mixing in the esterification pot. System and thermal oil heating system, change the temperature level of the thermal oil in the esterification pot thermal oil heater to 70-80 ° C. When the temperature level in the esterification kettle rises to 60 ° C, activate the vacuum system to leave the esterification pot. Refine to maintain the vacuum cleaner level in the esterification pot at -0.04 ~ -0.06 Mpa;

Step 2: Add the considered sebacic acid and the driver tetrabutyl titanate with a mass of 0.5% to 1% of the included sebacic acid right into the esterification pot of step 1. Afterwards, close the vacuum system and also place the sebacic acid in the esterification kettle. The products begin to react. When the temperature in the esterification kettle rises to 90 ~ 100 ℃, change the temperature of the warmth transfer oil in the heat transfer oil heater of the esterification pot to 200 ℃. When the temperature level in the esterification pot rises to 165 ~ 175 ℃, open up the esterification condenser to condense the products entering it. When reflux takes place in the esterification condenser, control the temperature level of the warmth transfer oil in the warm transfer oil heating unit of the esterification kettle to rise to 230 ° C at a heating rate of 10 to 20 ° C/h., when the temperature in the esterification kettle rises to 220 ° C, regulate the products in the esterification kettle to execute a temperature level and pressure-maintaining reaction at this temperature level for 25-35 minutes. After that, close the warm transfer oil furnace of the esterification pot to finish the esterification response;

Step 3. Deliver the products that have finished the esterification reaction in Step 2 to the rectification pot via the material pump in the pump distribution system. Afterwards, activate the vacuum system to leave the correction pot to preserve the vacuum in the rectification kettle. At -0.0985 ~ -0.099 Mpa, adjust the temperature level of the warm transfer oil in the warm transfer oil furnace of the purification kettle to 200 ° C, open up the distillation condenser to condense the products entering it;

Step 4: When the temperature at the top of the purification tower rises to 140-160 ° C, open up the valve of the alcohol finding storage tank to make sure that the alcohol receiving container gathers the isooctyl alcohol distilled at a temperature of 140-160 ° C at the top of the purification tower. When there disappears fluid flowing right into the alcohol receiving storage tank, readjust the temperature level of the warmth transfer oil in the warm transfer oil heating unit of the distillation pot to 290 ° C to make sure that the alcohol receiving container can continue to collect the distillate from the correction tower. When the temperature level at the top of the tower rises to 240-250 ° C, close the shutoff of the alcohol finding container as well as open the shutoff of the ester finding container to ensure that the ester receiving storage tank can accumulate the distillate distilled when the temperature level at the top of the purification tower goes beyond 240-250 ° C., the product gathered in the ester receiving container is the finished product diisooctyl sebacate.

In step 3, the materials that have actually completed the esterification response symphonious 2 require to be transferred by the product pump when the temperature of the esterification pot goes down below 180 ° C.
