Preparation of diethyl tin dicaprylate

The production of diethyl tin dicaprylate comprises four main stages the production and rectification of tetraethyltin the production of diethyl tin dichloride the production and drying of diethyl tin oxide the production of diethyl tin dicaprylate. 

The synthesis of diethyl tin dichloride is based on the reaction of tetraethyltin with tin tetrachloride  

Diethyl tin oxide enters the reaction with caprylic acid to form diethyl tin dicapiylate  

Raw stock magnesium chipping ethyl bromide (the boiling point is not less than 35 °C, d4° = 1.420- 1.445) diethyl ether (d420 0.714 0.715) benzene (the density is 0.8770-0.8791 g/cm3) tin tetrachloride (anhydrous, the boiling point is 114-115 °C) caprylic acid (the boiling point is 239-240 °C, d420 = 0.9089) potassium hydroxide (technical product). Ethyl bromide, diethyl ether and benzene are dried before use with calcium chloride.
