| titleOfInvention | Purification method for improving hydrolysis resistance of phosphate fire-resistant oil |
| abstract | The invention discloses a purification method for improving hydrolysis resistance of phosphate fire-resistant oil, belonging to the technical field of fire-resistant oil, comprising the following steps: adding a phosphate ester crude product and a solvent into a washing kettle, stirring and dissolving the phosphate ester crude product and the solvent, adding 1-5% alkaline water for alkali washing, heating and fully stirring, pumping the material into a layering tank through a centrifugal pump for standing, performing gravity settling separation, and putting the precipitated material into the washing kettle; repeatedly carrying out second alkali washing; putting the precipitate into the material in a washing kettle, adding deionized water for washing for the third time, and then carrying out layered precipitation; feeding the washed precipitate material into a wiped film evaporator, and evaporating the solvent, water and volatile matters; and finally, cooling the phosphate material, sampling and analyzing. The method is simple and convenient to operate, the phosphate crude product is dissolved by the organic solvent, and after the phosphate crude product is purified for many times by 1-5% alkaline water and deionized water, the hydrolysis stability HS of the prepared phosphate material is less than or equal to 0.05, so that the aim of improving the hydrolysis resistance of the phosphate fire-resistant oil is fulfilled. |
