How is solid alcohol made? Is the solid alcohol used in the hotel dry pot homemade or bought?

Solid alcohol is not solid alcohol (the melting point of alcohol is very low, it is-11℃, so it can't be solid at room temperature), but industrial alcohol (ethanol, CH3CH2OH) is added with coagulant to make it solid. There are four main methods, which can be found in/view/658053.htm. Generally, the production process of solid alcohol requires higher requirements, and carbon monoxide gas will be produced if inferior alcohol blocks are not fully burned. When the outside of industrial alcohol starts to burn, the inside does not get enough temperature and oxygen to fully reflect, so it can't be fully burned near the outside to produce carbon monoxide. Hotels use products from qualified manufacturers.
