1 results about "Sodium phenylacetate" patented technology

This invention provides a continuous acidification and separation device for sodium phenylacetate, belonging to the field of chemical equipment technology. It includes: a feeding unit, a separation unit, and a receiving unit connected sequentially by pipelines; the feeding unit includes a sulfuric acid storage tank, a sodium phenylacetate storage tank, and a first pipeline mixer, with the sulfuric acid storage tank and the sodium phenylacetate storage tank respectively connected to the first pipeline mixer via pipelines; the separation unit includes a separation tower, with an oil-water coalescing membrane assembly installed at the feed end of the separation tower; the first pipeline mixer is connected to the oil-water coalescing membrane assembly via pipelines; the receiving unit includes an oil phase receiving vessel and an aqueous phase receiving vessel; the oil phase pipeline at the top of the separation tower is connected to the oil phase receiving vessel, and the aqueous phase pipeline at the bottom of the separation tower is connected to the aqueous phase receiving vessel. This invention achieves effective separation of the phenylacetic acid oil phase and the sodium sulfate aqueous phase through the oil-water coalescing membrane assembly, solving the problem of unclear oil-water interface during the continuous acidification of sodium phenylacetate, which leads to low quality of the phenylacetic acid product.
