Embodiment 1

[0010] Example 1 Take 100 parts of palm oil, 50 parts of 50% hydrogen peroxide, 15 parts of formic acid, and 0.5 parts of concentrated sulfuric acid, react at 10°C for 48 hours, let stand to separate layers, discard the water layer, and use sodium hydroxide solution to neutralize the oil layer Afterwards, it was washed with deionized water until neutral, and the moisture was removed under reduced pressure to obtain the product. The epoxy value was 3.2.

[0011] figure 1 FTIR spectra of palm oil and epoxy palm oil.

[0012] In the FTIR spectrum, 3000cm -1 The stretching vibration absorption peak of C-H on the C=C double bond is at 830cm -1 is the asymmetric stretching vibration absorption peak of the epoxy group, by figure 1 Visible, in palm oil 3000cm -1 There are characteristic absorption peaks, and 830cm -1 There is no absorption peak at , indicating that there are double bonds in palm oil, but no epoxy bonds. And in the FTIR spectrogram of epoxy palm oil, at 3000cm ...

Embodiment 2

[0013] Example 2 Take 100 parts of palm oil, 70 parts of 30% hydrogen peroxide, 20 parts of acetic acid, and 3 parts of concentrated sulfuric acid, react at 100° C. for 0.5 hour, let stand to separate layers, discard the water layer, and use sodium carbonate solution to neutralize the oil layer. Then wash with deionized water until neutral, and remove water under reduced pressure to obtain the product. The epoxy value was 3.8.

Embodiment 3

[0014] Example 3 Take 100 parts of palm oil, 30 parts of peroxyformic acid, 1 part of concentrated sulfuric acid, and 5 parts of phosphoric acid, react at 60°C for 10 hours, leave to separate layers, discard the water layer, and neutralize the oil layer with sodium hydroxide solution , and then washed with deionized water until neutral, and the water was removed under reduced pressure to obtain the product. The epoxy value was 4.8.

Abstract

The invention provides a process for preparing an epoxy palm oil plasticizer, wherein the method, free from any dissolvent, uses palm oil as raw material and synthesizes the epoxy palm oil plasticiser by being reacted with epoxidizing agent on the catalytic action of concentrated sulphuric acid and / or phosphoric acid, under a certain temperature, time and proportioning. The epoxy palm oil plasticiser is used in the fields of plastics, paint industry, novel high molecular material, rubber, etc. wherein the working process does not bring in organic solvent waste liquid and noxious fumes to pollute the environment and harm the human body.

Description

(1) Technical field [0001] The invention relates to the field of organic compound synthesis, in particular to a production method of an epoxidized palm oil plasticizer. (2) Background technology Background technique [0002] For a long time, phthalates have played a major role in plastic plasticizers and are widely used. However, as research in recent years has found that phthalate plasticizers are toxic to the human body and even carcinogenic, they have been banned in many countries such as the United States and the European Union, and the source of phthalate plasticizers is In the petroleum industry, and petroleum is a non-renewable resource, with the soaring international oil price and the increasing shortage of petroleum resources, the invention of environmentally friendly plasticizers has become an inevitable trend of social development. [0003] Epoxidized soybean oil is an environmentally friendly plasticizer developed and applied earlier at home and abroad. It has...
