Problems solved by technology

[0004] Using a single oil to produce hydrogenated oil, due to the inherent defects of the raw material itself, there are some defects in the hydrogenated oil produced after hydrogenation, such as: the melting point of palm oil is not high and sticky before hydrogenation, although the melting point and hardness after hydrogenation It has been greatly improved, but its toughness and adhesion are still not good. The specific performance is that the product is hard and brittle, and the formability is not good; another example is soybean oil, which has a very low melting point before hydrogenation. It has been greatly improved but still does not meet the practical requirements, and hydrogenated soybean oil also has disadvantages such as low hardness and high preparation cost.

preparation example Construction

[0026] The method for preparing hydrogenated fats and oils, namely animal and vegetable waxes according to the present invention includes the following process steps:

[0027] 1. Mix the raw materials, take two or more kinds of vegetable fats and animal fats as raw materials to make the total ratio of them reach 100%, and then put them into the high pressure reactor, close the lid tightly, and stir at 650~1500rpm Fully mixed in the state;

[0028] 2. Add the catalyst, add the copper-nickel binary catalyst after the raw materials are fully mixed, and then fully stir and mix;

[0029] 3. Evacuate the hydrogenation system. After the raw materials and catalyst are fully stirred and mixed, the reactor is evacuated to 9.48×10 4 Pa vacuum degree, then fill the reaction kettle with 0.3~0.5Mpa nitrogen, release the pressure at the vent to 0.15MPa, and continue to vacuum to 9.48×10 4 The vacuum degree of Pa, maintain the vacuum state of the reactor after evacuating;

Abstract

The invention relates to a hydrogenated oil and fat, which is an animal and plant wax. The invention adopts two or more raw materials of palm oil, soybean oil, cottonseed oil, peanut oil, rapeseed oil, sesame oil, olive oil, corn oil, rice bran oil, coconut oil, cacao oil, sunflower seed oil, etc. plant oil and fat and beef tallow, sheep fat, pig fat, fish oil, etc. animal oil and fat. The raw materials are added with a copper-nickel binary catalyst and thoroughly mixed and then the hydrogenated oil and fat is prepared by a hydrogenation reaction when the mixture ratio reaches 100 per cent. The technique procedure of the preparation method is that: raw material mixture to adding catalyst to hydrogenation system vacuum pumping to hydrogenation system temperature rising to hydrogenation system hydrogen filling. The hydrogenated oil and fat of the invention has the good integrity performance of the high melting point, high hardness and high tenacity and strong adhesion; the invention haswide application, not only acts as a paraffin additive, but also as an animal and plant wax; the invention features the simpler operation, low manufacture cost and stronger market competition.

Description

【Technical Field】 [0001] The invention relates to the technical field of chemistry and chemical engineering. Specifically, it is a hydrogenated fat, namely animal and vegetable wax, prepared by using two or more vegetable fats and animal fats and adding a copper-nickel binary catalyst, and a preparation method thereof. 【Background technique】 [0002] At present, the hydrogenated fats and oils produced at home and abroad are basically made from a single fat, such as palm oil, soybean oil or other single fats. For example, Chinese patent CN90108548.7 describes a reaction process for producing alcohol by medium pressure hydrogenation using coconut oil or palm oil as raw materials. The specific preparation process is that coconut oil or palm oil is firstly esterified with methanol in the presence of alkali to produce methyl cocoate or methyl palmitoleate, and then hydrogenation is used to produce alcohol catalyst. Hydrogenation reaction is carried out to produce alcohol in a bed rea...
