Description

technical field [0001] The invention relates to a compound synthesis device, in particular to a production device of high-purity toluene as a pharmaceutical intermediate. Background technique [0002] High-purity toluene is widely used in the production of fine chemicals such as dyes, medicines, pesticides, auxiliaries, and spices, as well as in the synthetic material industry. Benzyl chloride, benzyl dichloride and benzyl trichloride obtained by side chain chlorination of toluene, including their derivatives benzyl alcohol, benzaldehyde and benzoyl chloride, the ring chlorination products of toluene are intermediates of pesticides, medicines and dyes . Toluene is oxidized to obtain benzoic acid, which is an important food preservative and also used as an intermediate in organic synthesis. Intermediates obtained by sulfonation of toluene and benzene derivatives, including p-toluenesulfonic acid and its sodium salt, CLT acid, toluene-2,4-disulfonic acid, benzaldehyde-2,4-di...
