The product uses of cinnamate

1. Cinnamate is mainly used in food additives, cosmetics and pharmaceutical intermediates.

2. Cinnamic acid can be used for antiseptic, antiseptic and antiseptic of food, vegetables and fruits.

3. Cinnamate can also brighten it in wine. It has a strong excitatory effect and can be directly added to all foods widely.

4. Cinnamic acid ester is also a component of capsaicin synthase cinnamic acid hydrolase, which can be used to breed capsaicin-rich varieties with high yields, which will greatly improve the quality of peppers and effectively promote the industrialization of peppers.

Synthesis and properties of a photochromic dye-containing two optical functional groups of spiropyran and cinnamate

Photochromic dyes have received widespread attention due to their potential application prospects in optical and optoelectronic fields such as data storage, display materials or optical operations. The spiropyran structure is a type of organic photochromic dye that has been studied more. Usually, the spiro carbon atoms on the spiropyran structure, under the irradiation or heating of ultraviolet light (λmax=250~300nm), transform from sp3 hybridization to sp2 hybridization, forming a planar open ring body, which can develop colour.

At present, restricting the application of such compounds in the industry is mainly due to the poor thermal stability of the colour bodies after the photochromism of such compounds. Research and development of relatively stable colour bodies are still photochromic dyes A hot topic of research.

The photopolymerization process is another important type of photochemical reaction. Cinnamate is one of the photosensitive compounds, and the polymer material grafted with cinnamate can be used as a photosensitive material. Its film can occur under the irradiation of ultraviolet light (2π +2π) photopolymerization reaction.
