There are many synthetic routes of 10-hydroxy-2-decenoic acid, and the following is one of the possible synthetic routes:
(1).Hydroxymethylation of isopropyl acetate: isopropyl acetate is heated with methanol and sodium hydroxide in a reactor to obtain a mixture of methyl acetate and isopropyl acetate. The mixture was then reacted with sodium hydroxide under high temperature and pressure to obtain the precursor of 10-hydroxy-2-decenoic acid, 10-methoxy-2-decenoic acid methyl ester.
(2).Hydrogenation of 10-methoxy-2-decenoic acid methyl ester: 10-methoxy-2-decenoic acid methyl ester is heated and reacted with hydrogen and catalyst (such as platinum catalyst) in the reactor to obtain 10-hydroxy-2-decanoic acid methyl ester.
(3).Hydroxylation reaction: 10-hydroxy-2-decenoic acid methyl ester is reacted with iodine and sodium hydroxide in a reactor to obtain 10-hydroxy-2-decenoic acid.
(4).Esterification reaction: 10-hydroxy-2-decenoic acid is reacted with activator (such as dimethyldichlorosilane) and acylation reagent (such as propionyl chloride) in the reactor to obtain the esterification product of 10-hydroxy-2-decenoic acid, such as 10-hydroxy-2-decenoic acid propyl ester.
To sum up, the synthesis route of 10-hydroxy-2-decenoic acid includes hydroxymethylation of isopropyl acetate, hydrogenation, hydroxylation and esterification of 10-methoxy-2-decenoic acid methyl ester.
As for the commonly used countries and the annual export volume of 10-hydroxy-2-decenoic acid, the data may vary due to the different production and consumption demands between different countries and regions. Here are some possible data for reference:
(1) China: China is one of the major producers of 10-hydroxy-2-decenoic acid in the world. According to the data of China Customs, China's export volume of 10-hydroxy-2-decenoic acid in 2019 was 121 tons.
(2) United States: The United States is also one of the producers of 10-hydroxy-2-decenoic acid. According to the data of the United States Customs, the export volume of 10-hydroxy-2-decenoic acid from the United States in 2019 was 21 tons.
(3) Europe: Europe is also one of the main production and consumption areas of 10-hydroxy-2-decenoic acid. However, the data of Europe is often the statistics of the whole EU. According to EU data, the export volume of 10-hydroxy-2-decenoic acid in 2019 was 128 tons.
It should be noted that these data are for reference only, and actual data may vary. In addition, because the application demand of 10-hydroxy-2-decenoic acid is different in different countries and regions, the change of export volume may be affected by many factors, including market demand, production cost, etc.
