Embodiment 1

[0066] (1) Pretreatment of castor bean seeds at 0.5Kg: removing impurities and pests, shelling, drying and crushing to obtain castor bean powder;

[0067] (2) Put the castor bean powder obtained in step 1 into a container, add 1.5L of petroleum ether-diethyl ether mixed solvent with a volume ratio of 9:1 (material-to-liquid ratio 1:3); stir and extract with an electric stirrer at room temperature 1 time, 60min extraction; the power of the electric stirrer is 50W, and the speed is 2rpm;

[0068] (3) Filtering and separating the solid-liquid mixture obtained in step 2 to obtain mixed oil and castor meal; the mixed oil is vacuum desolventized to obtain 0.1557Kg castor oil with a leaching rate of 58.05%.

Embodiment 2

[0070] Castor bean 0.5Kg, using a preparation method similar to Example 1; the difference lies in:

[0071] The volume ratio of petroleum ether and ether in the mixed solvent is 7:3, and the rotating speed of the electric stirrer is 4 rpm.

[0072] The castor oil 0.2158Kg was prepared, and the extraction rate was 80.43%.

Embodiment 3

[0074] Castor bean 0.5Kg, using a preparation method similar to Example 1; the difference lies in:

[0075] The volume ratio of petroleum ether and ether in the mixed solvent is 5:5, and the rotating speed of the electric stirrer is 5 rpm.

[0076] 0.1903kg castor oil was prepared, and the leaching rate was 70.95%.

Abstract

The invention provides a preparation method of castor oil. The preparation method comprises the following steps: crushing castor seeds, and lixiviating through a solvent to obtain a mixed deoiling solvent, wherein the solvent is a mixed solvent which comprises petroleum ether and diethyl ether; preferably, the volume ratio of the petroleum ether and the diethyl ether which are contained in the mixed solvent is 5:5-9:1; the massive volume ratio of the castor seeds and the mixed solvent is 1:1-1:7. The preparation method provided by the invention has the advantages of high lixiviating efficiency and less energy consumption. The invention also provides the castor oil prepared through the preparation method.

Description

Technical field [0001] The invention belongs to the field of oil industry or chemical technology, and specifically relates to a preparation method for extracting castor oil by using a mixed solvent and castor oil prepared therefrom. Background technique [0002] Castor (Ricinus communis) is an annual or perennial herbaceous plant of the Euphorbia family (Euphoribia L). It is one of the top ten oil crops in the world. It is widely planted all over the world. The main producing areas are India, China, Brazil and other countries. More than 90% of the world's production. In my country, castor oil is mainly produced in Inner Mongolia, Jilin, Shandong and Shanxi. Castor seeds have a high oil content, accounting for about 45-55% of the weight of the seeds. The castor oil contained in it is the only natural fatty acid that contains hydroxyl groups and has special physical and chemical properties. Castor oil is an important chemical raw material, widely used in chemical, textile, light ...
