Embodiment 1

[0033] Add 6.406g (0.05mol) of 2,5-furandimethanol, 11.104g (0.12mol) of n-butyric acid, 0.1g of p-toluenesulfonic acid and 8ml of toluene into a three-neck flask with a condensing reflux device and a water separator. After being heated to the first drop of toluene and starting to reflux, continue to reflux for 4 hours, then carry out vacuum distillation to obtain 2,5-furandimethanol dibutyrate, and its infrared spectrum and nuclear magnetic resonance spectrum are shown in figure 1 and figure 2 .

Embodiment 2

[0035] Add 6.406g (0.05mol) of 2,5-furandimethanol, 14.081g (0.11mol) of n-hexanoic acid, 0.15g of p-toluenesulfonic acid and 10ml of toluene into a three-necked flask with a condensing reflux device and a water separator. After heating until the first drop of toluene starts to reflux, continue to reflux for 5 hours, and then carry out vacuum distillation to obtain 2,5-furandimethanol dihexanoate.

Embodiment 3

[0037] Add 6.406g (0.05mol) of 2,5-furandimethanol, 20.924g (0.13mol) of n-octanoic acid, 0.15ml of concentrated sulfuric acid and 12ml of toluene into a three-necked flask with a condensing reflux device and a water separator. After being heated to the first drop of toluene and starting to reflux, continue to reflux for 6 hours, then carry out vacuum distillation to obtain 2,5-furandimethanol dioctanoate, its infrared spectrum and nuclear magnetic resonance spectrum are shown in image 3 and Figure 4 .

Abstract

The invention discloses a 2,5-furandimethanol diester plasticizer, which is as shown in the formula (I), and discloses a preparation method of the 2,5-furandimethanol diester plasticizer. The preparation method comprises the following steps of, under the protection of an inert gas, carrying out esterification reaction on 2,5-furandimethanol and monocarboxylic acid under the joint action of a catalyst and a water carrying agent, and carrying out post treatment on a reaction product to obtain the 2,5-furandimethanol diester plasticizer. The plasticizer has the characteristics of no toxicity, environmental friendliness and the like, is used as a plastic plasticizer and has the advantage that a raw material can be regenerated; the dependency on a petrochemical resource when a plasticizer is prepared is greatly decreased, and meanwhile, the environmental pollution problem brought by a conventional petroleum-based plasticizer is solved at the same time. The formula (I) is shown in the description.

Description

technical field [0001] The invention belongs to the field of organic synthesis, and specifically relates to a 2,5-furandimethanol diester plasticizer and a preparation method thereof. Background technique [0002] The most widely used plasticizers in the plastic processing industry are phthalate plasticizers. Because their synthetic raw materials are mainly derived from petroleum, this type of plasticizer is called petroleum-based plasticizer. Since its industrial production, petroleum-based plasticizers have developed rapidly in the high-density material industry due to their excellent performance. However, with the depletion of petrochemical resources and the increasing awareness of environmental protection, the negative effects of phthalate plasticizers are gradually revealed. For example, phthalate plasticizers are classified as suspected environmental hormones, which can cause endocrine disorders, miscarriages, birth defects, deformed children, and cause malignant tumo...
