反应式如下:
Materials: Naphthostyril [130-00-7] 已上网。 Hydrochloric acid 700 kg。 Brine as necessary。
Procedure: 操作步骤:
The batch (naphthostyril) is then blown onto 1000 l. cold water, and cooled to 20 – 25℃. Hydrochloric acid is then added in sufficient quantity to make it nearly neutral (300 l.).
It is then blown via screening press into a stirred vessel containing 1600 kg. ice and 400 l. hydrochloric acid. The temperature must not rise above 10℃. Then further acid is added to make the batch acid to methyl orange.
The precipitated aminonaphthoic acid is filtered on a nutsche and washed free from acid with brine.
Yield = 700 – 800 kg. paste. ≈145 kg. dry (M.W. 187) = 91.9% theory.

The melt (naphthostyril) is transferred to a 5500 liter, cast iron, jacketed kettle, in which has been previously placed 1000 liters of water and after being well mixed, the charge is cooled by means of the jacket to 20 – 25℃.
350 kilograms of hydrochloric acid (31.5%) are then added slowly under the surface of the slurry, by means of a rubber lined pipe dipping below the surface of the charge.
This acid is added to cut down the bulk of alkalinity of the charge, which should still be alkaline at the end of the addition. The volume of the charge at this point should be about 2500 liters.
The temperature is now adjusted to 25℃ and a sample sent to the laboratory, after which the charge is blown into a 6000 liter acid proof brick lined tank in which has previously been placed 1600 kilograms of ice and 560 kilograms of hydrochloric acid (31.5%).
Under these conditions with the temperature kept below 10℃, sulfur dioxide gas is evolved and foaming takes place and the 1-carboxy-8-amino naphthalene is precipitated.
The addition of hydrochloric acid is continued in small portions until a permanent acid reaction is obtained on Congo Red paper, avoiding, however, any large excess of acid. The slurry is then allowed to agitate for one hour and is filtered on a porous stone nutsch of three square meters filter atea.
The nutsch layer is washed with 200 liters of 50Be’ salt solution, through the kettle, then with two portions of 400 liters each of 50Be’ salt solution, being careful to avoid cracks in the layer.
The nutsch cake, which is nearly white in color, is sucked down well on the nutsch, and no color of sulfur dioxide should be apparent at this point.
Yield = 700 – 800 kilograms of paste = 172 kilograms dry equivalent (100% Mol. Wt.) = 93% of theory.
