Abstract
The invention relates to environmentally-friendly military solid alcohol fuel. The optimal technical conditions comprise that a reaction temperature is 70 DEG C, the solid alcohol fuel comprises 1.60% of a dispersant, 4.46% of stearic acid, 0.62% of NaOH, 90.73% of industrial ethanol and 2.59% of distilled water. The product is milky, has fine and uniform gel particles and large hardness, is convenient for storage and can be randomly cut by a small knife.
Description
Technical field
The invention belongs to the military solid alcohol fuel of a kind of environment-friendly type, is a kind of solid alcohol fuel, belongs to chemical technical field.
Background technology
Solid fuel as a kind ofly carrying with, safe ready, economical and practical food and drink thermal source be widely used in dual-use.On military thermal source, urotropine solid fuel is owing to there being larger intensity at normal temperatures, and be convenient to storage, and calorific value is higher, thus so far still as fuel needed for individual combat.But, due to the feature (molecular formula is (CH2) 6N4) of its chemical property, during burning, easily produce the oxynitrides to human body and bad environmental, and not easily Thorough combustion, a large amount of black smoke can be produced, polluting heating apparatus, making troubles to reusing, particularly in high altitude anoxia situation, burning quality is low, be difficult to play solid-fuelled advantage, and the price of raw material urotropine is higher, the market competitiveness is poor.Therefore, the state such as German, Japanese has developed and has replaced the solid-fuelled solid alcohol fuel of urotropine.Although a variety of novel solid alcohol fuel has also appearred in China in recent years, because of advantages such as homogeneous flame temperature, safely cleaning, easy to use and carrying conveniences, be widely used in fuel for chafing dish.But owing to forming the defect in the chemical composition of gel and preparation technology, these solid alcohol fuels still exist a lot of deficiency at present, in preparation process, just easily there is local gelling phenomenon, be difficult to realize industrialized continuous seepage; And hardness is inadequate, and can not preserve for a long time.Therefore, the requirement of quartermaster equipment exhibition area can't be met.
Searching can meet all needs the needs equipped to be the developing direction studied from now on, this research with stearic acid and sodium hydroxide for gelifying agent, adopt two-step synthesis, interpolation can change gel microstructure, increase solid fuel physical strength, and improve the dispersion agent of solid fuel stability, by the saponification reaction of routine, significant quantities of fat alcohol is made to be wrapped in the mesh skeleton of stearic acid sodium salt firmly, development security is good, combustion heat value is high, shelf lives is long, be applicable to the environment protection solid alcohol ate in high altitude anoxia area, contrast existing military solid urotropine fuel and Canadian military liquid fuel, investigate its combustionvelocity, fusing point, combustioncharacteristics under the heat-processed of water and low pressure, to the military solid fuel of alternative tradition.
Summary of the invention
The exploitation of novel process and raw-material industrialization are for guarantee quality product, and it is very important for reducing product cost.Therefore, industrial goods starting material are selected in the selection of raw material as far as possible, the proportion by weight scope of this product is ethanol industry product 30-50, purity >=95%; Stearic acid: industrial one-level 40-70; Sodium hydroxide: chemical reagent 30-60, analytical pure; Dispersion agent: industrial goods 40-80; Distilled water 60-80.
For heat source, use water bath with thermostatic control and ultrasonic heater, to control temperature of reaction.Laboratory apparatus adopts three mouthfuls of glass flask liquid seal devices, and electric mixer, reflux condensing tube and mercurythermometer are housed respectively.
Optimum process condition: temperature of reaction is 70, DEG C, the chemical composition of solid alcohol fuel is respectively dispersion agent 1.60%, stearic acid 4.46%, NaOH0.62%, industrial alcohol 90.73%, distilled water 2.59%; Product appearance is creamy white, gel particle uniform and delicate; Hardness is large, and storage is convenient, and available pocket knife arbitrarily cuts.
The fusing point of solid alcohol fuel is 52, DEG C, calorific value is-28.44kJ/g, and combustionproperty is stablized; Rate of combustion and burning area have exponential relationship, disclose quantitative combustion law; Ignition is easy, does not produce black smoke and obnoxious flavour, environmentally friendly, is applicable to high altitude anoxia area.
Embodiment
Industrial alcohol, stearic acid and dispersion agent are added with in churned mechanically three mouthfuls of glass flask liquid seal devices respectively by certain mass ratio, is then placed in water bath with thermostatic control, starts agitator, until solid stearic acid raw material dissolves completely.Meanwhile, separately get an Erlenmeyer flask, add a certain amount of solid NuaO and a small amount of distilled water, make it to dissolve, then add the industrial alcohol of requirement, be placed in the water-bath of ultrasonic constant-temperature well heater, limit is stirred, and limit is heated, until aqueous sodium hydroxide solution disperses in ethanol completely.Then sodium hydroxide ethanolic soln is slowly joined in stearic acid ethanolic soln, carry out acid-base reaction, obtain limpid sodium stearate ethanolic soln, then pour into while hot in model-container, make its curing molding.
