WebOther Syntheses of Phthalimide-protected Amino Groups. A convenient, efficient, and selective N-Alkylation of N-acidic heterocyclic compounds with alkyl halides is accomplished in ionic liquids in the presence of potassium hydroxide as a base. In this manner, phthalimide, indole, benzimidazole, and succinimide can be successfully alkylated. WebStructure, properties, spectra, suppliers and links for: N-(PROPARGYLOXY)PHTHALIMIDE, 4616-63-1.

Web(ii) Ethylamine is soluble in water whereas aniline is not: Ethylamine when added to water forms intermolecular H−bonds with water. Hence, it is soluble in water. But aniline does not undergo H−bonding with water to a very large extent due to the presence of a large hydrophobic −C 6 H 5 group. Hence, aniline is insoluble in water. WebAmines also display some solubility in water. However, the solubility decreases with an increase in carbon atoms, due to the increased hydrophobicity of the compound as the chain length increases. Aliphatic amines, which are amines connected to an alkyl chain, display solubility in organic polar solvents. cyndy short attorney

WebPhthalimide may be recrystallized from water, but only about 4 g. of phthalimide will dissolve in a liter of boiling water. It may also be crystallized from alcohol, in which solvent it dissolves to the extent of five parts in a hundred at boiling temperature. 4. WebAug 13, 2004 · Abstract. The invention relates to a process for preparing N-methyl-o-phthalimide, which comprises, using benzoic anhydride as raw material, purging methylamine gas for reaction at the presence of inert gas without solvent, dripping water-soluble solvent after the reaction finishes, depositing N-methyl-o-phthalimide crystal, … WebIt is practically insoluble in water at room temperature and is only slightly soluble in organic solvents. The technical product is 90% pure. The impurities in the technical product consist of up to 4.5 percent phthalimide, up to 2.5 percent water, up to 2.5 percent calcium carbonate, and less than 1 percent unidentified products. billy loughnane height
