AI Technical Summary

Benefits of technology

This patented method involves synthesizing two different types of molecules called chlorophylls (vitamins) from carboxylic acids: VC-phosphonates with hydroxyl groups on one side compared to those without them. These compounds have improved stability against photooxide attacks while still maintaining their beneficial properties for use by humans or other organisms like plants.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving how much it works when used alone or together for various purposes like healthcare applications where they are commonly found alongside other substances that help fight diseases on their own.

Embodiment Construction

[0012] Processing step of the present invention is:

[0013] 1. Synthesis of 5,6-O-isopropylidene-vitamin C

[0014] Add 100-150ml of acetone to a 250ml three-neck flask equipped with a reflux condenser, turn on the constant temperature water bath and electric stirrer, and then quickly add quantitative vitamin C so that the amount of acetone and vitamin C is 10:1-20: 1. Add 5-10ml of catalyst hydroiodic acid, heat and stir at 25-30°C for 2-3 hours, filter under reduced pressure after the reaction, wash the product repeatedly with acetone and n-hexane, and dry it in vacuum;

[0015] 2. Synthesis of Magnesium Ascorbyl Phosphate

[0016] Add 8:1~10:1 mixed solution of distilled water and pyridine into a 250ml four-necked flask, then place it in an ice-water bath and stir, protect with nitrogen, then add 5,6-O-isopropylidene-vitamin C, and use Add phosphorus oxychloride dropwise to the dropping funnel, so that the ratio of the amount of 5,6-O-isopropylidene-vitamin C and phospho...
