It was first synthesized by Heffer, which was prepared by slightly boiling sponge palladium in the presence of a small amount of nitric acid and refluxing glacial acetic acid. Later, after several improvements, the nitric acid was changed to perchloric acid, oxygen, NO+O2, NO2, NO+NO2, etc. At the same time, it could also be prepared by adding glacial acetic acid to hot palladium sulfate aqueous solution.
However, its process has obvious disadvantages:
(1) The reflux reaction time is long, the operation is complex, and the reaction is incomplete, and the batch increase makes the performance more outstanding;
(2) If oxygen is used as oxidant, the reaction should be conducted at 810614kPa, and the equipment and operation are complex;
(3) The sources of NO, NO2 and other raw materials are difficult;
(4) The above reaction may produce a pink insoluble polymer without catalytic activity.
Sponge palladium can be obtained by direct reaction of palladium chloride with aqueous solution of sodium hydroxide and sodium formate, and then it can react with acetic acid and catalytic amount of nitric acid to obtain it by reflux for half an hour. However, it is reported in the literature that water soluble palladium chloride is used as raw material, which is expensive, and is also washed with acetone, which is not environmentally friendly.
To sum up, since acetic acid is a weak acid, and sponge palladium has surface oxidation and other problems, the key to improve the synthesis of palladium acetate is the preparation of activated palladium (also known as palladium black). It is reported in the literature that palladium black can be prepared by reducing the aqueous solution of palladium chloride with molecular hydrogen, formaldehyde water and aldehyde in the ethanol system, or by using the ammonia solution of palladium chloride to make it alkaline and then reducing it with formic acid, Activated palladium can also be obtained by reducing palladium chloride with sodium borohydride. However, a key step in all the above processes is that no matter sponge palladium or palladium black is used as palladium source, nitric acid is used in the preparation process, so Pd (OAc) · NO2 by-products are inevitably generated. N-O vibration peak can be clearly seen in the infrared spectrum, affecting the product quality. Therefore, the judgment of reaction reflux time is that reddish brown gas is no longer generated, and the time can be shortened by adding palladium black, But sometimes the problem cannot be solved fundamentally. Hangzhou Kaida Catalytic Metal Materials Co., Ltd. has successfully selected a suitable reductant to prepare highly active product based on years of experience in the synthesis of noble metal properties and noble metal compounds, and solved the problem of Pd (OAc) · NO2 by-products by improving the equipment. The product quality is stable and reliable.
