Chlorophyll copper sodium salt is a dark green powder, which is made from natural green plant tissues, such as silkworm dung, clover, alfalfa, bamboo and other plant leaves, and extracted with acetone, methanol It is extracted with organic solvents such as acetone, methanol, ethanol, petroleum ether, etc., and replaced the central magnesium ion of chlorophyll with copper ion, and saponified with alkali to remove the methyl and phytol groups to form the carboxyl The carboxyl group formed after the removal of methyl and phytol groups becomes a disodium salt. Thus, chlorophyll copper sodium salt is a semi-synthetic pigment. Other pigments in the chlorophyll family with similar structure and production principle include sodium salt of chlorophyll iron, sodium salt of chlorophyll Zinc sodium salt, etc.
Sodium chlorophyll copper salts are mainly composed of disodium chlorophyll copper and trisodium chlorophyll copper. It is easily soluble in water and ethanol solution, and the aqueous solution is transparent bright green, deepening with increasing concentration. It is light and heat resistant and has good stability.
Chlorophyll is one of the natural bioactive substances, and metalloporphyrin, as a chlorophyll derivative, is the most unique one among all natural pigments and has a wide range of applications. As a kind of metalloporphyrin, copper sodium salt of chlorophyll has high stability, and metalloporphyrin is widely used as food additive, cosmetic additive, colorant, medicine, light conversion material, etc. It is widely used as food additive, cosmetic additive, colorant, pharmaceutical, photoelectric conversion material and other fields.
With the strengthening of people's awareness of environmental protection and the increasing attention to health, the negative effects of synthetic dyes used in textile dyeing on human health and the ecological environment The use of non-polluting green natural dyes for dyeing textiles has become a research direction for many scholars. There are few natural dyes that can be dyed green, and Chlorophyll copper sodium salt is a kind of food-grade green color pigment, which is a natural chlorophyll derivative and can be refined by saponifying and coppering the extracted chlorophyll. It is a kind of metal porphyrin with high stability, dark green powder, slightly metallic luster.
It can be added to cosmetics as a coloring agent. Chlorophyllin copper sodium salt is a dark green powder, odorless or slightly odorous. The aqueous solution is transparent emerald green, deepening with increasing concentration, light and heat resistant, with good stability, The pH of 1% solution is 9.5~10.2, when the pH is below 6.5, it can produce precipitation when it meets calcium. Slightly soluble in ethanol. Easily precipitated in acidic beverages. Stronger than chlorophyll in light resistance, decomposes when heated above 110℃. In view of its stability and low toxicity, chlorophyll copper sodium salt is widely used in the cosmetic industry.
The development of organic dye-sensitized wide-band semiconductor photovoltaic cells was started in the 1990s. The photovoltaic electrode of the dye-sensitized photochemical substrate model consists of a wide-band, porous, large surface area semiconductor on which dyes sensitive to the visible spectrum are adsorbed. Due to the large surface area and porosity of Ultra Particle Film (UPF) Due to the large surface area and porosity of UPF, research on the construction of efficient photochemical substrates on UPF crystal electrodes has made rapid progress. Some researchers have prepared a model of SnO2 ultraparticle film photochemical substrate The photoelectrochemical substrate with sandwich structure was designed and fabricated using copper chlorophyll sodium salt as sensitizer and 1-/13- as redox pair to study its photoelectric conversion mechanism.
Sodium chlorophyllin copper salt is basically harmless to human body. Moreover, the sodium chlorophyllin copper salt is easily absorbed by human body and has the effect of promoting metabolism to the body cells, also can promote the healing of gastrointestinal ulcer surface and promote the liver function. It can also promote the healing of gastrointestinal ulcers and the recovery of liver function.
