solid alcohol is the best for hot pot restaurants.

solid alcohol, which is convenient to use, transport and carry, causes less environmental pollution when burning, and is safer than liquid alcohol. As a solid fuel, it is widely used in catering, tourism and field work. At very low temperature, because stearic acid can't be completely dissolved, solid alcohol can't be made. Stearic acid can be dissolved at 31℃, but it takes a long time. And solid alcohol is generated immediately after the two liquids are mixed, and the uniformity of the generated products is poor because of the too fast curing speed. With the increase of temperature, the uniformity of cured products is getting better and better. At 61℃, the two liquids do not solidify immediately after mixing, so the solution can be mixed very evenly. After mixing, the alcohol will solidify continuously in the process of natural cooling, and finally a uniform solid alcohol will be obtained. The prepared solid alcohol can still be kept in a solid state during combustion. In this way, the safety of solid alcohol in use is greatly improved, and the cost can be reduced at the same time. In some occasions, plastic bags can be used instead of iron drums or plastic drums. Especially when working in the field or traveling, solid alcohol can be burned directly on iron plates or bricks without being put in iron drums, which is particularly convenient to use. When the amount of stearic acid is increased, solid alcohol will have a hard film when burning, which prevents the alcohol from flowing and keeps the solid form of alcohol.
