Embodiment Construction

[0013] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0014] 1.1 Experimental principle

[0015] Solid alcohol is not alcohol that turns liquid alcohol into a solid form, but uses a solidifiable substance to carry alcohol, and contains alcohol in it to make it solid. The reaction that will occur when stearic acid is mixed with sodium hydroxide:

[0016] C 17 h 35 COOH+NaOH=C 17 h 35 COONa+H 2 o

[0017] The sodium stearate produced by the reaction is a long carbon chain polar molecule, which forms a three-dimensional skeleton with a network structure under heating conditions, and is evenly distributed in the alcohol. After cooling, the sodium stearate solidifies and wraps the alcohol molecules in In a solid structure, a solid alcohol product is formed.

Abstract

The invention discloses a preparation method of solid alcohol, and obtains the best preparation process of solid alcohol when potassium permanganate is used as a combustion aid and stearic acid is used as a curing agent: the mass ratio of alcohol to stearic acid is 40:1, adding When 4% distilled water is used, the hardness is better compared with other proportions, adding a mass ratio of 0.014% potassium permanganate combustion accelerant can improve the combustion performance of solid alcohol, eliminate black smoke, reduce calorific value loss, and reduce the amount of residue; and On the basis of no additional cost increase, the cooling conditions are changed to improve its combustion performance. Keeping the pH value at about 8 can make the solid alcohol coagulate best. The solid alcohol prepared under the above conditions has the characteristics of high hardness, less residue, high heat release, easy storage, safety and portability, and can be used in catering, tourism, field operations and other industries.

Description

technical field [0001] The invention belongs to the technical field of chemistry and relates to a preparation method of solid alcohol. Background technique [0002] Solid alcohol (also known as "alcohol block") is a fuel that is safe to use, easy to carry, economical, non-polluting, and has the advantages of easy ignition, uniform flame temperature, and small calorific value deviation. At present, it has been widely used in catering industry, tourism industry and field operation and other industries. Some of the solid alcohol currently used on the market has poor storage stability, and after being placed for a period of time, it will become soft, paste-like, and liquid oozes out; some emit black smoke when burning, have peculiar smell, and pollute the environment; Black particles will come in and out, causing dust pollution; some are not resistant to burning and have a flow phenomenon when burning; some have more residues after burning and a series of shortcomings. In orde...
