| Application | salicylaldehyde derivatives in organic analysis, complex catalyst ligand synthesis, there are a wide range of applications in the synthesis of drugs and fine chemicals. Salicylaldoxime has important applications in the determination of Pt, Cu, Zn, Ni and Pb sensitive analytical reagents, β-receptor blocker bunirole synthesis intermediates. The method is used for the determination reagent and determination of copper ion content in water environment, which is a solution in which a copper developer is dissolved in an organic phase; The copper developer is salicylaldoxime and/or salicylaldoxime derivative. |
| preparation | dissolve 14.6g(0.21mol) of hydroxylamine hydrochloride in 40ml of water and place in a ML round bottom flask, A total of 16.8g(0.20mol) of NaHCO3 was added in portions to clarify; With vigorous stirring, 24.4g of salicylaldehyde and 40ml of 95% ethanol were added, and heated to reflux in an oil bath with a rotary evaporator for 1H, TLC test showed no residual salicylaldehyde. Heating was stopped and the mixture was slightly cooled, and most of the ethanol was distilled off under reduced pressure. Suction filtration, water (10ml x 3), dry white crystals after a total of 26.5g, the yield was 96.7%. |
| Use | reagents for the determination of platinum, copper, zinc, copper and nickel. |
| production method | salicylaldehyde was dissolved in sodium hydroxide solution, and hydroxylamine hydrochloride was added. The mixture was heated on a water bath for half an hour and adjusted to Neutral with glacial acetic acid. Upon cooling in an ice bath, salicylaldoxime was precipitated. After Benzene recrystallization, and then containing a small amount of benzene of petroleum ether recrystallization, that is to get the finished product. |
