Problems solved by technology

The solid fuel product prepared in this way still has many deficiencies: first, the melting point is relatively low and cannot be stored for a long time at a higher temperature; Industrialized continuous production; Third, under the conditions of low air pressure and insufficient oxygen, the combustion vacuum is insufficient and the duration is short, so it cannot be used in high-altitude environments
Therefore, it cannot meet the equipment requirements of military solid alcohol fuel

Embodiment 1

[0038] Embodiment 1, the preparation of solid alcohol fuel

[0039] Raw materials: 1.3 grams of paraffin, 4.76 grams of stearic acid, 0.62 grams of NaOH, 90.73 grams of industrial alcohol, and 2.59 grams of distilled water.

[0040] Adopt two-step method to prepare solid alcohol fuel, experimental procedure is:

[0041] In the first step, stearic acid is dissolved in alcohol. The specific operation is as follows:

[0042] ①The temperature of the water bath in the fixed constant temperature water tank is 70°C, and the stirring speed of the electric stirrer is 250r / min.

[0043] ② Weigh stearic acid, paraffin and 50.55 grams of industrial alcohol respectively, and add them into a three-necked flask in turn. Then install an electric stirrer, a thermometer and a reflux condenser on the three-neck flask.

[0044] ③Heat and stir the three-necked flask in a water bath. A small amount of evaporated alcohol is condensed by the reflux condenser and returned to the three-necked flask...

Embodiment 2

[0049] Embodiment 2: the influence of each factor when preparing solid alcohol fuel

[0050] This example examines in detail the factors that have an impact on the quality of solid alcohol fuel products. In this experiment, the heating time in the water bath was 10 minutes, the mixing reaction time was 2 minutes, and the mechanical stirring speed was 250 r / min. Wherein the alcohol (alcohol 1) consumption is 50.55g in the three-necked flask, and the alcohol (alcohol 2) consumption is 40.18g (the whole material benchmark is 100g) in the Erlenmeyer flask.

[0051] 1. The influence of temperature

[0052] Based on the melting point of stearic acid being 67-70°C, the experimental temperature t=60°C, 65°C, 70°C, and 75°C were taken as four levels to investigate the influence of temperature on the experiment and the product.

Embodiment 3

[0079] Embodiment 3, the performance test of solid alcohol fuel

[0080] The solid alcohol fuels of the present invention used in this example are prepared by optimizing the process conditions and raw material ratios in Example 2. The similar product (reference substance 1) of contrast, raw material industrial alcohol 500ml, sodium hydroxide 2.5g, stearic acid 14.5g, paraffin 4.0g, water 10g are that main raw material is processed with the same process with embodiment 2. The control sample urotropine (reference substance 2) military solid fuel was purchased from Beijing Dongxin International Health Products Co., Ltd.

[0081] 1. Melting point experiment of solid alcohol fuel:

[0082] Experiment method: carried out in a stable super constant temperature water bath, the specific operation steps are as follows:

[0083]Before the measurement, lower the temperature of the water bath to 40°C, fix the small Erlenmeyer flask with the sample in the water bath, and heat it slowly. ...

Abstract

The present invention discloses one kind of solid alcohol fuel, which is prepared with industrial alcohol 90.73 wt%, stearic acid 4.76 wt%, NaOH 0.62 wt%, paraffin 1.30 wt% and distilled water 2.59 wt%, and through two steps at temperature of 70deg.C. The solid alcohol fuel has easy ignition, high heat value, no black smoke and bad smell produced during burning and other features. Especially, it can burn stably in anoxic condition, so that it is suitable for use in plateau and upland.

Description

technical field [0001] The invention relates to a solid fuel, in particular to a portable, safe, easy-to-store and transport high-calorific-value solid alcohol fuel and a preparation method thereof. Background technique [0002] As a portable, safe, convenient, and economical food and beverage heat source, solid fuel has been widely used in military and civilian applications. As a heat source for military use, urotropine solid fuel has greater strength at room temperature, is easy to store, and has a high calorific value, so it is still used as a fuel for individual combat and is widely used in foreign or domestic troops. . The product is white solid, can be used outdoors, is easy to carry, and is not volatile. However, due to the characteristics of its chemical properties (molecular formula is (CH 2 ) 6 N 4 ), it is easy to produce nitrogen oxides that are harmful to the human body and the environment when burning, and it is not easy to burn fully, it will produce a lo...
