acetaldehyde sodium bisulfite
1.THE CRYSTAL STRUCTURE OF THE ADDITION PRODUCT OF ACROLEIN WITH SODIUM BISULFITE
2.And then, environmental friendly water treatment agents of acrylic acid-3- allyoxy-2 -hydroxy-1-propanesulfonic acid salt copolymer is produced by copolymerization. In this paper, at first, the intermediate of sodium 3-choro-2-hydroxy propanesulfate was synthesized from epichlorohydrin ad sodium bisulfite.
4.METHODS Mainly through adding Sodium bisulfite and Calcium Disodium Edtate to prevent propygallate from being oxidated as well as chromogenic reaction with metal ions,adjusting pH 3.0～5.0 with hydrochloric acid,the quality of activated charcoal used is 0.02% of the solution,sterilization using moist heat must be done at 115℃ for 30 minutes.
