Second, the Synthetic Route we will recommend is the most important for your reference?

First, synthesis line of Tetraethylammonium hydroxide CAS NO.77-98-5 as follows

Main production methods:

1. First dissolve tetraethylammonium chloride in methanol, then add the theoretical amount of potassium hydroxide methanol solution, mix thoroughly, and potassium chloride will precipitate:

After the reaction is complete, let it stand and filter under reduced pressure. The filtrate obtained is added to water for reduced pressure distillation to remove alcohol and water, so that the content of tetraethylammonium hydroxide in the solution reaches 44%. Then, it is dried under vacuum, and the resulting crystals are the finished product.

2. First dissolve tetraethylammonium iodide in water to make it a 15% solution, then add the theoretical amount of silver oxide, heat in a water bath and keep warm to complete the reaction:

Other synthesie lines as follows,
