Properties and stability
N-Phenylmorpholine is a fairly stable compound and does not easily catch fire. Chemical properties pKa 3.20 (25°C, water). Condensation with benzaldehyde produces a colorless matrix, which is rearranged to obtain malachite green dye. Due to the presence of morpholino group, the ortho-para position of the benzene ring is activated and reacts with nitric acidObtain ortho and para nitro compounds. It is relatively stable to oxidation and only generates a small amount of formaldehyde when oxidized with dichromic acid.
Storage method
This product should be kept sealed.
Synthesis method
Prepared by the action of N, N-bis-β-hydroxyethylaniline and sulfuric acid.
Purification method: Use water for recrystallization and purification.
Purpose
The compound has properties similar to N, N-dimethylaniline and is basic. It can be used as a reagent for dehydrobromination of allyl bromide compounds and has the advantage that the product is easier to purify. Used as anti-corrosion additives, intermediates for dyes and insecticides, and catalysts in the decomposition of peroxides.
