Description

Phosphoric acid is a colorless, odorless, crystalline solid or a thick syrupy liquid. Physical state is strength and temperature dependent.
Concentrated phosphoric acid occurs as a colorless, odorless, syrupy liquid. It has a pleasing acid taste when suitably diluted.
Pure phosphoric acid, also called orthophosphoric acid, is a clear, colorless, mineral acid with moderate strength. It is normally marketed as an aqueous solution of 75–85% in which it exists as a clear, viscous liquid

Usage

Mainly used in phosphate industry, electroplating, polishing industry, sugar industry, compound fertilizer, etc. In the food industry as a sour agent, yeast nutrient, etc.; mainly used as a catalyst for ethylene hydration to produce ethanol, high-purity phosphate, pharmaceutical manufacturing, and chemical reagents. Mainly used in the preparation of chemical fertilizers, detergents, food and feed additives, flame retardants and various phosphates; commonly used as analytical reagents; used for volume and colorimetric analysis, etc.; in the production of silicon flat tubes and integrated circuits, it is common Using aluminum film as electrode lead requires photolithography of aluminum film and phosphoric acid as an acid cleaning etchant. Can be formulated with acetic acid. It can be used as a sour agent and a nutrient for yeast. It can be used as a sour agent for seasoning, canned food, and refreshing drinks. It is used as a source of yeast nutrition during wine making to prevent the reproduction of miscellaneous bacteria.

Production Methods

1. Industrial production methods are wet and heat. The former system of phosphoric acid concentration is low, and contains more impurities, the need for purification. For example, 85% of industrial phosphoric acid has been produced by refining the wet - process phosphoric acid by the extraction system of ketone - alcohol mixture, and the extraction - washing - stripping and barium salt precipitation purification process. The latter phosphoric acid concentration and purity are high, but the power consumption, investment and higher cost. Wet method is the use of acid decomposition of phosphorus ore. This method is divided into sulfuric acid, hydrochloric acid, nitric acid and ammonium hydrogen sulfate method. Commonly used sulfuric acid method. Sulfuric acid method due to the reaction temperature and the concentration of phosphoric acid produced in different phosphoric acid solution calcium sulfate crystals in three different forms, according to their production process is divided into
