Yield:3588-30-5 58%

Reaction Conditions:

with potassium hydrogensulfate

Steps:

A.B

1 ,3,3-Trimethoxybutane was dropped slowly into a heated distilling flask containing 0.1 g of potassium bisulfate. The 1 ,3,3-trimethoxy compound was added at such a rate that approximately 20 g was present in the flask. The temperature of the flask was maintained at 140 °C to cause steady distillation of the decomposition products, . e., methyl alcohol and 2- methoxybuta- l ,3-diene. The decomposition products were collected in 5% potassium carbonate solution and by further washing with potassium carbonate solution followed by drying and distilling. From 70 g of the 1 ,3,3-trimethoxy compound there was obtained in this manner 23 g of 2-methoxybuta-l ,3-diene (58% conversion)..
