Embodiment 1

[0015] Mix 266.20g (2mol) of aspartic acid powder with 56.10g (1mol) of calcium oxide powder, slowly add 40.0mL of distilled water dropwise, and stir to granulate. After granulation, the material was dried in an oven at 60°C for 5 hours to obtain the finished product of calcium aspartate.

Embodiment 2

[0017] Mix 53.24kg (400mol) of aspartic acid powder with 11.22kg (200mol) of calcium oxide powder, add 11.0L of distilled water, and granulate with a granulator. After granulation, the material was dried in an oven at 80°C for 4 hours to obtain the finished product of calcium aspartate.

Embodiment 3

[0019] Mix 266.2g (2mol) of aspartic acid powder with 74.1g (1mol) of calcium hydroxide powder, slowly add 35.0mL of distilled water dropwise, stir and granulate. After granulation, the material was dried in an oven at 60°C for 5 hours to obtain the finished product of calcium aspartate.

Abstract

The invention relates to a room-temperature solid-phase synthesis method of calcium aspartate. The method comprises the following steps: evenly mixing aspartic acid powder and calcium oxide or calcium hydroxide powder in a mole ratio of 2:1, granulating by a wet process, reacting at room temperature, and directly drying to obtain the calcium aspartate finished product. The method has the advantages of simple technique and low energy consumption, and can enhance the production efficiency and lower the production cost.

Description

technical field [0001] The invention relates to a method for synthesizing calcium aspartate in solid phase at room temperature. Calcium aspartate is obtained by mixing aspartic acid powder with calcium oxide or calcium hydroxide powder at a molar ratio of 2:1, and reacting at room temperature through wet granulation. Background technique [0002] Calcium aspartate is a compound with a five-membered ring structure consisting of 2 molecules of L-aspartic acid and 1 molecule of calcium ion chelated, including a calcium ion. The center of the molecule is a calcium atom, and the two sides are symmetrical An amino acid molecule, like a crab clamping the calcium atom in the center, forms a chemical structure of two stable five-membered rings. Its molecular formula is C 8 h 12 o 8 N 2 Ca, relative molecular mass 304.2. Calcium aspartate is in the form of white powder, with physical and chemical characteristics such as odorless, hygroscopic, easily soluble in water, insoluble i...
