What is the synthesis method of 2,6-anthracene disulfonic acid, 4,8-diamino-9,10-dihydro-1,5-dihydroxy-9,10-dioxo-
To prepare 2,6-naphthalene dicarboxylic acid, 4,8-dihydroxy-9,10-dihydro-1,5-diamino-9,10-dioxo compound, the method is as follows:
First, naphthalene is used as a group, and a specific group is introduced through several steps. First, the naphthalene is mixed with a specific reagent under suitable conditions to induce 1,5-diamine to be based on the naphthalene ring. This step requires selecting appropriate temperature, pressure and catalyst to make the reaction smooth and highly selective. Or by using the method of amination, a specific aminating agent is used to react with naphthalene in the catalytic system to obtain an intermediate of 1,5-diaminonaphthalene.
Then, the intermediate is oxidized and 9,10-dioxo is introduced. Often reacted with oxidizing reagents, such as strong oxidizing metal salts or peroxides, in suitable solvents. Control the reaction conditions, and the dioxo-preserving group is formed at the position 9,10.
Furthermore, a carboxyl group is introduced at the position 2,6 of the naphthalene ring to form the structure of 2,6-naphthalic acid. This step may be carried out by carboxylation reaction, with carbon monoxide and suitable reagents, and the carboxyl group is introduced under the catalytic action.
As for the introduction of 4,8-dihydroxyl groups, the 4,8-naphthalene ring can be hydroxylated with a hydroxylating reagent at an appropriate time. Among them, the selection of suitable reagents and the control of reaction conditions are the most important, which are related to the purity and yield of the product. After each step of the reaction, it needs to be separated and purified to remove impurities and obtain high-purity intermediates or end products. Each step is connected and strictly operated to obtain the target 2,6-naphthalene dicarboxylic acid, 4,8-dihydroxy-9,10-dihydro-1,5-diamino-9,10-dioxo compound.
