Embodiment 1

[0027] Sodium ferric chlorophyll is dissolved in water with a solution concentration of 0.67g / 100ml. Anhydrous strontium chloride is dissolved in water. Add the strontium salt solution into the ferric chlorophyllin sodium salt solution, stir at a speed of about 1000r / min, and make it fully react at room temperature. Aged at 17°C for 7h. Separation by filtration and drying at 50°C for 3 hours to obtain black (dark green) ferric strontium chlorophyllin salt. Carry out the measurement of each index. Wherein, by AVATAR360 type Fourier transform infrared spectrometer, UV7652 spectrophotometer, obtain iron chlorophyllin sodium salt and chlorophyllin iron strontium salt spectrogram (see attached Figure 1~4 ), and analyzed and compared, it was determined that the product was ferric strontium chlorophyllin.

[0028] The calculated yield was 75%.

Embodiment 2

[0030] Sodium ferric chlorophyll is dissolved in water with a solution concentration of 0.67g / 100ml. Anhydrous strontium chloride is dissolved in water. Add the strontium salt solution into the ferric chlorophyllin sodium salt solution, stir at a speed of 1000r / min, and make it fully react at room temperature. Aged at 20°C for 8h. Separation by filtration and drying at 50°C for 3 hours to obtain black (dark green) ferric strontium chlorophyllin salt. Carry out the measurement of each index.

[0031] The calculated yield was 78%.

Embodiment 3

[0033] Sodium ferric chlorophyll is dissolved in water with a solution concentration of 0.67g / 100ml. Anhydrous strontium chloride is dissolved in water. Add the strontium salt solution into the ferric chlorophyllin sodium salt solution, stir at a speed of 1000r / min, and make it fully react at room temperature. Aged at 25°C for 9h. Separation by filtration and drying at 50°C for 3 hours to obtain black (dark green) ferric strontium chlorophyllin salt. Carry out the measurement of each index.

[0034] The calculated yield was 80%.

[0035] Chlorophyll iron strontium salt analysis:

[0036] 1. Judging from the changes in the experimental phenomena, after dissolving sodium iron chlorophyllin in water, the color of the solution is dark green, adding Sr 2+ When the solution becomes salt, a black precipitate is produced immediately, indicating that new substances are formed.

[0037] 2. Ultraviolet-visible absorption spectrum (UV) analysis

[0038] See attached figure 1 , 2 a...

Abstract

The invention discloses a natural strontium ferrous chlorophyllin (also known as ferrous chlorophyllin strontium) and a preparation method thereof. According to the method, sodium ferrous chlorophyllin and strontium salts are taken as raw materials, replacement is directly performed, and preparation is finished by one single step. The method includes solving the sodium ferrous chlorophyllin and the strontium salts in water according to a mass ratio, adding the strontium salt solution into the sodium ferrous chlorophyllin solution, magnetically stirring at a speed of about 1000r/min, reacting fully at a room temperature, aging, separating, drying for 3 hours at a temperature of 50 DEG C, and obtaining black (deep black green) strontium ferrous chlorophyllin with a yield of about 75%-80%. The product proved to be the strontium ferrous chlorophyllin through color changes, generation of precipitation, an ultraviolet (UV) spectrogram and an infrared radiation (IR) spectrogram during the preparation. The preparation method is simple, low in cost and high in yield, produces no side products, and has no environmental pollution; the raw materials required for the synthesis are easy to obtain, low in price, non-toxic and innocuous; and the strontium ferrous chlorophyllin and the preparation method have a huge development and application prospect in medical drugs, function materials and the like.

Description

technical field [0001] The invention relates to a natural pigment salt and a preparation method thereof, in particular to a preparation method of natural iron strontium chlorophyll salt. The obtained natural strontium iron chlorophyll salt is also called strontium iron chlorophyllin. Background technique [0002] Chlorophyll derivatives: Sodium copper chlorophyllin, sodium zinc chlorophyllin and sodium iron chlorophyllin are important pharmaceutical and biochemical products, widely used in daily chemical industry, food industry and pharmaceutical products. [0003] In the modern battery industry, strontium is a new type of energy storage material, and strontium is also one of the components of superconducting metal oxides, and has become a widely used functional material. [0004] At the same time, strontium (Sr) is also an essential trace element for the human body, and is a normal component of human bones and teeth. There is also a lot of strontium in the parts with stro...
