Are amines soluble in petroleum ether?

Question

Are butylamine and dibutylamine soluble in petroleum ether? my lab results show that when butylamine is added to petroleum ether, it floats but dissolve after a while. why is it so? and why doesnt dibutylamine dissolve in petroleum ether?

Answer 1

The larger the organic chain of the amine, the readily it will dissolve.

Dibutyl amine is probably not dissolving due to trace amounts of moisture present.

Answer 2

We all know organic produce is grown without the use of pesticide but what else? Well organic farmers encourage wild plants and animals to share the land with them. They use compost and other natural fertilizers instead of chemical ones. They are generally small family farms and therefore do most of the tilling, planting and harvesting by hand without the use of polluting machines. They usually use "heritage" or "heirloom" seeds rather than genetically engineered ones. They're products are usually delivered to the public at local farmers markets or stores which cuts down on the use of fossil fuels for delivery. Then when you get them home they have no pesticide residue or chemical waxes on them to get into you. And there's more! Eggs laid by free range chickens have less cholesterol, less saturated fat, more vitamin A, more omega-3 fatty acids, more vitamin E, and more beta carotene. Animals raised on "free range" are naturally higher in omega-3 fatty acids and lower in fat and cholesterol when compared to grain feed animals. And think about this! The run off from feed lots, large scale dairies and egg operations is considered a toxic substance and has to be handled as such. Because they have to live in a toxic waste dump the animals antibiotics, pesticides, and other hazardous chemicals have to be used to keep the animals "healthy".
