ましい。In the present invention, the amount of organic acid salt of alkoxyalkylamine added to dichlorofluoroethane is usually 0.01.
A range of ~10% by weight is preferable; if the amount added is small, the dehydration ability will not be sufficient, and if it is too large, a large amount of surfactant will remain on the surface of the product, causing lumps and surface contamination. Therefore, the range of 0.1 to 5% by weight is particularly preferable.
