Problems solved by technology

[0004] The traditional coconut oil preparation is obtained by hydrolysis-distillation of raw material oil. The proportion of components in the product of coconut oil depends entirely on the raw materials, and the proportion of components cannot be flexibly changed.

Embodiment 1

[0145] Such as figure 1 Shown technological process prepares coconut oil, specifically comprises the following steps:

[0146] 1) High temperature and high pressure countercurrent hydrolysis step

[0147] Select crude palm kernel oil (CPKO) as the raw material oil, and the index of this batch of CPKO is as follows: iodine value 19gI 2 / 100g, Lovibond color 60Y6R, free fatty acid (calculated as palmitic acid) 3.1%, moisture 0.25%, saponification value 247mgKOH / g, fatty acid component ratio: C6 0.21%, C8 2.99%, C10 3.05%, C12 47.56%, C14 16.35%, C16 8.72%, C18:02.24%, C18:1 15.87%, C18:2 2.85%, other fatty acids 0.16%.

[0148] Send CPKO and water (including steam) into the hydrolysis equipment according to the mass ratio of 100:75, and maintain the reaction temperature at 250°C and the pressure at 5.2MPa to obtain crude fatty acid. Moisture and unhydrolyzed oils.

[0149] 2) Fatty acid vacuum fractionation step

[0150] Then the crude fatty acid is sent into the dryer, mai...

Embodiment 2

[0159] It is basically the same as Example 1, except that the hydrogenated caprylic acid / capric acid mixed fatty acid product, lauric acid product, myristic acid product and unhydrogenated C16-C18 mixed fatty acid product are according to 1.5:5.0:1.7:1.8 The ratio is compounded to obtain a partially hydrogenated coconut oil product. Its index compares as shown in table 2 with the hydrogenated coconut oil product index that the conventional process shown in comparative example 2 produces.

[0160] From the data in Table 2, it can be found that the sample in the present embodiment, due to the special production process steps in the present embodiment, makes the color and luster of the product, thermal stability all significantly better than traditional coconut oil products, and the freezing point is lower than traditional coconut oil Acid products. The product of this embodiment is a mixture with a low freezing point, and at room temperature, it has better anti-separation perfo...

Embodiment 3

[0174] The flow process of this embodiment is different from that of Example 1 in that the fatty acid decompression fractionation step adopts 3 fractionation towers, according to image 3 Controlled by the process mode, a variety of fractionated fatty acid products can be obtained, including caprylic acid / capric acid mixed fatty acid (caprylic acid + capric acid mass content > 95%), lauric acid / myristic acid mixed fatty acid (lauric acid + myristic acid content > 98%) %), palmitic acid / stearic acid / oleic acid / linoleic acid mixed fatty acid (C16~C18 mixed fatty acid for short).

[0175] Correspondingly, in the fatty acid continuous hydrogenation step, the lauric acid / myristic acid mixed fatty acid is directly hydrogenated to obtain hydrogenated lauric acid / myristic acid mixed fatty acid.

[0176] In the fatty acid compounding step, the hydrogenated caprylic acid / capric acid mixed fatty acid product, lauric acid / myristic acid mixed fatty acid product and C16-C18 mixed fatty ac...

Abstract

The invention relates to a method for producing cocoic acid and cocoic acid produced by the method. The production method of the coconut oil of the present invention comprises: (1) hydrolyzing raw material oil; (2) separating and obtaining fatty acid components; and (3) compounding fatty acid components. The coconut oil produced by the method of the invention has good quality and stable properties, and the freezing point and fatty acid composition range of the product are wider than the coconut oil produced by the traditional method, and the indicators can be flexibly adjusted according to the specific needs of different industries. Compared with directly mixing various fatty acids, the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of oil deep processing, in particular to a production method of coconut oil and coconut oil prepared by the method. Background technique [0002] Coconut oil, white solid or light yellow liquid at room temperature, is caprylic acid, capric acid, dodecanoic acid, tetradecanoic acid, hexadecanoic acid, octadecanoic acid, octadecanoic acid It is a mixture of various natural fatty acids such as enoic acid, and is widely used in the synthesis or compounding of daily washing, industrial detergents, papermaking additives, and chemical fiber oils. [0003] With the rapid development of the daily liquid washing industry and industrial washing industry in recent years, cocoic acid is one of the main raw materials, and the market demand is bound to grow rapidly. However, there are many types of components contained in coconut oil, and the proportions of different components are different, which will also cause differe...
