Problems solved by technology

[0003] However, the ultra-clean and high-purity isopropanol used in the microelectronic chemical industry has very strict requirements on the particle size content and anions of metal impurities, and the metal impurities and anions contained in isopropanol may not be effectively removed only by rectification equipment. Anions, and thus can no longer meet the industrial requirements, for this reason, we propose an ultra-clean high-purity isopropanol preparation equipment

Abstract

The invention discloses ultra-clean high-purity isopropanol preparation equipment which comprises a base, a raw material mixing tank and a driving motor, a feeding port is formed in the raw material mixing tank, raw materials are fed into the raw material mixing tank through the feeding port, a hydraulic push rod is started to drive a piston rod to move, then a piston is driven to move, and therefore adding of a complexing agent is controlled quantitatively; then a driving motor is started to drive a deflection plate to rotate, then a supporting column is driven to rotate to sequentially jack up the edge of a fixed disc, a raw material mixing tank is driven to shake mixed materials, meanwhile, a first shaft is driven to rotate through a universal joint assembly, a stirring shaft is driven to rotate through a magnet in a rotating disc, a first fluted disc is driven to rotate, and then a second fluted disc is driven to rotate; according to the technical scheme, the raw material mixing tank and the stirring rod are driven to synchronously and reversely rotate to stir and mix the materials, so that the isopropanol raw material and the complexing agent are uniformly and quickly mixed, the complexing agent is used for adhering metal ions in isopropanol, the metal ions are settled, and the content of the metal ions in the isopropanol is effectively removed.

Description

technical field [0001] The invention relates to the technical field of isopropanol preparation, in particular to an ultra-clean and high-purity isopropanol preparation equipment. Background technique [0002] With the rapid development of semiconductor technology, the requirements for ultra-clean and high-purity reagents are getting higher and higher. During the processing of integrated circuits, ultra-clean and high-purity reagents are mainly used for cleaning and etching the surface of chips and silicon wafers. Purity and cleanliness have a very significant impact on the yield, electrical properties and reliability of integrated circuits, and ultra-clean and high-purity isopropyl alcohol, as an important microelectronic chemical, has been widely used in semiconductor and large-scale integrated circuit processing. In terms of cleaning and drying in the process, as the processing size of integrated circuits enters the sub-micron and deep sub-micron era, higher requirements a...
