A method for producing a series of candle special waxes

Abstract

The invention discloses a method for producing series special waxes for candlelight. The method comprises: hydrorefining Fischer-Tropsch synthetic wax to obtain Fischer-Tropsch refined wax; separatingthe Fischer-Tropsch refined wax to obtain a plurality of distillate waxes; selecting the et distillate wax from the distillate waxes, heating the target distillate wax to completely melt, naturally cooling, carrying out programmed cooling to achieve a specified temperature so as to form a solid state with a crystal structure, heating to a first temperature, and collecting a first distillate oil melted at the first temperature at a constant temperature; continuously heating to a second temperature, and collecting a second distillate oil melted at the second temperature at a constant temperature so as to be used as a first candlelight wax product; and continuously heating to different preset temperatures, and collecting distillate oils melted at the preset temperatures at a constant temperature until the distillate wax is completely melted. According to the invention, the method does not require deoiling processing, and has characteristics of simple processing technology, low operationtemperature, low energy consumption and low investment cost, wherein the thermal stress of the wax is small so as to achieve the low color change of the product.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a method for producing a series of candle special waxes. Background technique [0002] The raw materials for making existing candles are mainly paraffin wax extracted from petroleum and a mixture based on paraffin wax, and some auxiliary materials are added accordingly. The paraffin wax used in candle production has various practical uses, and the quality requirements are also different. Generally, the quality of candles mainly depends on the composition and melting point of paraffin wax raw materials. Use paraffin as raw material to produce candles. After the paraffin is refined, it is separated into several types with melting points of 52, 54, 56, 58 and 60°C. It can also be obtained by mixing paraffins with different melting points in different proportions. [0003] The traditional candle preparation method is prepared by fractionating petroleum componen...

Problems solved by technology

In existing reports, Fischer-Tropsch synthetic refined wax and Fischer-Tropsch synthetic cracked wax composition are used to prepare candles. The Fischer-Tropsch synthetic cracked wax needs to be subjected to high-pressure hydrocracking operations, and the production process has harsh operating conditions and potential safety hazards.
