Irritating to skin. See other resources 02 UK Patent Application. Documen tapped on or after the declared priority meanwhile but before the thesis date of this invemion. In each Taurocholic acid synthesis meaning Individualsa base as specified in Table 1 was ran to the reaction xoixture in an meta of 0. An loom of the present invention is to provide a random and efficient process for producing crystals of 3-aminohydroxyacetophenone sample, which are easily handled for industrial purposes and have hired bulk density and improved flow properties. Deltas, aromatic hydrocarbons, water, and mixtures of two or more of these are interested.

Modified acetophenone-formaldehyde resins are produced by the hydrogenation of the aforementioned ketone-containing resins. The resulting polyol can be further crosslinked with diisocyanates.

Niche uses[ edit ] Acetophenone is an ingredient in fragrances that resemble almond , cherry , honeysuckle , jasmine , and strawberry. The 3-aminohydroxyacetophenone represented by formula 1 or its hydrogen halide salt which are to be treated, e.

The catalytic reduction is usually carried out in a solvent. Alcohols, aromatic hydrocarbons, water, and mixtures of two or more of these are preferred. The amount of the solvent is usually about 2 to about 10 grams, preferably about 3 to about 6 grams, per 1 gram of nitro compound represented by formula 2. After the reactiori is completed, the catalyst is generally removed, e - g - separated from the reaction mixture following the reduction, such as by filtration.

In the latter case, instead of 3-aminohydroxyacetophenone, an Inorganic halide, such as an alkali metal or ammonium halide, e. After the treatment with base, the catalyst and the precipitated inorganic halide can be removed simultaneously, such as by filtration. The amount of base should be sufficient to make 3-aminohydroxyacetophenone dissolve in the solvent, and is usually 0. Although the 3-amino hydroxyacetophenone 1 or its hydrogen halide salt thos obtained can be isolated by distillation, recrystallization, or another treatment, the reaction 10 solution after the removal of the catalyst is generally used as the raw material which is treated with sulfuric acid in a solvent according to the present invention.

The nitro compound of formula 2 is Jcnown and can be prepared by the application or adaptation of known IS methods, for example, according to the method disclosed in Japanese Patent KORAl Publication Nc. The amount of solvent depends upon the type of solvent used in the sulfuric acid treatment step, but is suitably selected within a range generally from about 2 to about 10 times the weight of 3-aminohydroxyacetophenone or its hydrogen halide salt to be treated.

The amount of sulfuric acid is generally from about 1 to about 10 moles, preferably about 2 to 4 moles, per one aole of 3-aniinohydroxyacetophenone or its hydrogen halide salt.. Sulfuric acid is usually added in 0. After the addition of sulfuric acid, the sulfuric acid treated mixture may be aged for 1 to 3 hours - Generally, the 3-aminohydroxyacetophenone salt crystalizes out.

However, in case the treatment with sulfuric acid in water or solvent containing water as a major component results in insufficient precipitation of the crystals of 3-aminohydroxyacetophenone salt, e. Another possible method is to remove water with another solvent by azeotropxe.

This method is, however, less favored because energy inefficient and time-consuiung. Skin: Get medical aid.
