Abstract
The invention relates to a waste edible oil gel and a preparation method thereof. The gel is carried out at normal temperature and normal pressure, and is extremely simple. More importantly, the content of the waste edible oil in the gel can reach 17% -21%, which is 1.7-2.1 times of the content of the gel of the waste edible oil reported at present. Today, the problem of waste edible oil is increasingly prominent, and the material has important significance. In addition, the modified material has good production prospect and can be further popularized and applied.
Description
Technical Field
The invention belongs to the technical field of comprehensive utilization of waste edible oil, and relates to waste edible oil gel and a preparation method thereof.
Background
The reuse of waste edible oils has become an important and urgent issue. From the current report, the comprehensive utilization of the waste edible oil mainly comprises the following three aspects: firstly, direct combustion; secondly, converting the fuel into biodiesel by a certain means; thirdly, the fuel made into solid glue or similar solid alcohol burns (Waste Manag.85 (2019) 295-303). In contrast, the third method is low in cost and safe, however, the content of the waste edible oil is less than 10% in the report of preparing gel or similar solid alcohol by using the waste edible oil, and the utilization rate is low.
Disclosure of Invention
Technical problem to be solved
In order to avoid the defects of the prior art, the invention provides a waste edible oil gel and a preparation method thereof.
Technical proposal
The waste edible oil gel is characterized by comprising the following components in percentage by mass: 30% of ethyl cellulose, 26% -30% of ethyl acetate, 23% of nano calcium hydroxide and 17% -21% of waste edible oil.
The waste edible oil comprises waste rapeseed oil, waste corn oil or waste peanut oil.
The preparation method of the waste edible oil gel is characterized in that the whole preparation process is carried out at normal temperature and normal pressure; after completely dissolving ethyl cellulose in butyl acetate, adding nano calcium hydroxide, stirring for 30-60 minutes to completely disperse nano calcium hydroxide powder, finally adding waste edible oil, stirring for 60-100 minutes, and standing for 12-24 hours to obtain the waste edible oil gel.
The waste edible oil comprises waste rapeseed oil, waste corn oil or waste peanut oil.
The preparation of the nano calcium hydroxide comprises the following steps: the preparation of nano calcium hydroxide is described in the previously issued patent (ZL 201711361358.7); firstly, adding dimethylformamide into a calcium chloride solution, and stirring to obtain a calcium chloride mixed solution; and then pouring the calcium chloride mixed solution into a sodium hydroxide solution to synthesize nano calcium hydroxide, washing the synthesized nano calcium hydroxide with saturated lime water, and finally drying to obtain nano calcium hydroxide powder.
Advantageous effects
According to the waste edible oil gel and the preparation method thereof, ethyl cellulose is firstly dissolved in butyl acetate, then nano calcium hydroxide and waste edible oil are added, and the waste edible oil gel is obtained after stirring for a period of time. The gel is carried out at normal temperature and normal pressure, and is extremely simple. More importantly, the content of the waste edible oil in the gel can reach 17% -21%, which is 1.7-2.1 times of the content of the gel of the waste edible oil reported at present. Today, the problem of waste edible oil is increasingly prominent, and the material has important significance. In addition, the modified material has good production prospect and can be further popularized and applied.
Compared with the prior art, the preparation method of the waste edible oil gel is simple and convenient, and the whole process is carried out at normal temperature and normal pressure. The gel preparation process does not need complex operation and only needs simple stirring. More importantly, the content of the waste edible oil in the synthesized waste edible oil gel can reach 17% -21%, which is 1.7-2.1 times of the content of the waste edible (waste rapeseed oil, waste corn oil and waste peanut oil) oil gel reported at present, and the utilization rate of the waste edible oil is greatly improved.

Wherein the mass percentages of the ethyl cellulose, the ethyl acetate, the nano calcium hydroxide, the waste rapeseed oil or the waste corn oil or the waste peanut oil are respectively 30%,28%, 23% and 19%.
Embodiment III:
dissolving ethyl cellulose in butyl acetate completely, adding nano calcium hydroxide, stirring for 50 minutes to completely disperse nano calcium hydroxide powder, adding waste edible oil (waste rapeseed oil, waste corn oil and waste peanut oil), stirring for 90 minutes, and standing for 20 hours to obtain waste edible oil gel. Wherein the mass percentages of the ethyl cellulose, the ethyl acetate, the nano calcium hydroxide, the waste rapeseed oil or the waste corn oil or the waste peanut oil are respectively 30%,29%, 23% and 18%.
Embodiment four:
dissolving ethyl cellulose in butyl acetate completely, adding nano calcium hydroxide, stirring for 60 minutes to completely disperse nano calcium hydroxide powder, adding waste edible oil (waste rapeseed oil, waste corn oil and waste peanut oil), stirring for 100 minutes, and standing for 24 hours to obtain waste edible oil gel. Wherein the mass percentages of the ethyl cellulose, the ethyl acetate, the nano calcium hydroxide, the waste rapeseed oil or the waste corn oil or the waste peanut oil are respectively 30%,30%, 23% and 17%.
While the present invention has been described in detail through the foregoing description of the preferred embodiment, it should be understood that the foregoing description is not to be considered as limiting the invention. Many modifications and substitutions of the present invention will become apparent to those of ordinary skill in the art upon reading the foregoing. Accordingly, the scope of the invention should be limited only by the attached claims.
