Description

TECHNICAL FIELD

[0001] The utility model relates to centrifugal device technical field, concretely is a kind of ethyl-2-(phenylaminooxy) propionamide recrystallization mother liquor processing with centrifugal device. BACKGROUND

[0002] Ethyl-2-(phenylaminooxy) propionamide recrystallization mother liquor is residual liquid obtained after ethyl-2-(phenylaminooxy) propionamide is subjected to recrystallization operation and filtered. Generally, the mother liquor contains a certain amount of ethyl-2-(phenylaminooxy) propionamide that is not crystallized out, impurities introduced in the recrystallization process, and solvent used for recrystallization. The composition and content are affected by the recrystallization conditions (such as solvent, temperature, and concentration) and the purity of the original substance. If the solvent has strong solubility to the substance, more of the substance may remain in the mother liquor. If impurities are introduced, they may also be present in the mother liquor. The treatment of the mother liquor depends on the situation. If there is a lot of target substance, it can be further purified or the conditions can be adjusted to improve the yield. If the impurities are difficult to separate, special treatment or disposal as waste is required.

[0003] When the mother liquor is processed, a centrifugal device is needed to process the mother liquor. The mother liquor may contain small solid particles, including undissolved impurities or a small amount of product crystals. The centrifugal force generated by the high-speed rotation of the centrifugal device can quickly settle the solid particles, achieving solid-liquid separation and facilitating subsequent treatment of the liquid components or recovery of the solids. Second, for some small or sticky particles in the mother liquor, the separation effect of centrifugal operation is better than that of traditional filtration. The traditional filtration method is prone to blockage of filter paper and other media due to the formation of a viscous system by impurities and solvent. The centrifugal device can avoid the problem of blockage and efficiently separate the solid components. However, the existing centrifugal device cannot be adjusted as a whole, which makes it inconvenient for workers to discharge the processed mother liquor from the centrifugal device.
