2-Methoxyethylmercury chloride is a chemical compound from the group of organic mercury compounds .

Extraction and presentation

2-Methoxyethylmercury chloride is produced by reacting mercury (II) acetate with ethene in methanol to form (2-methoxyethyl) mercury acetate and precipitating the chloride with sodium chloride.

properties

2-Methoxyethylmercury chloride is a crystalline white solid that is practically insoluble in water. It decomposes when heated.

use

2-Methoxyethylmercury chloride is or has been used as a fungicide . The effect is based on the reaction with the sulfhydryl group in fungal germs and inhibits growth. It was used as an active ingredient in liquid dressings and wet dressings. Its use has been banned in Canada and the USA since 1971. According to the Plant Protection Application Ordinance, there is a complete ban on the use of mercury compounds in Germany. In Australia, the use of 2-methoxyethylmercury chloride in fungicides for use on sugar cane plantations is permitted. Due to the fact that Australia is a signatory to the Minamata Convention , their use will have to be replaced by mercury-free fungicides.

safety instructions

2-Methoxyethylmercuric chloride decomposes on contact with mineral salts to form ethylene , methanol and inorganic mercury salts.
