However, if gun-cotton be dissolved in a suitable solvent, which is capable of being evaporated out, such as acetone, or acetate of ethyl, which are very volatile, it becomes, when thus dissolved and dried, a very hard, horn-like, amorphous substance, which may be used for a smokeless gunpowder.
But between the purely synoptic formula and the very elaborate formula there are others contracted formulae which labor under the disadvantage, as a rule, of being one-sided, and so create a false impression as to the nature of the substance. The only plan is to use them variously and capriciously, according to the reaction to be explained. Again, ethyl acetate may be written Or condensed
They sent Ethyl home to die, giving her a few days to a month at most. Any sensible hygienist trying to stay out of jail would have refused to take on this type of case because it was a cancer case where death was likely.
Liquid irritants soon came to the front xylyl bromide and xylylene dibromide a mixture used later under the name of T. stuff, bromo-acetone and brominated methyl ethyl ketone, later introduced under the name of B. stuff and Bn. stuff."
Truly chemistry works wonders. Take ethyl alcohol, or ordinary spirits of wine, and add four more atoms of carbon to the carbon molecule, and we have the poison carbolic acid. Pure alcohol can be turned into a deadly poison, not by adding to, but simply by taking from it; take out one atom of carbon and two of hydrogen from the alcohol molecule, and we have the poison methyl alcohol.
So with reference to the question of atomic and molecular combination, as atomic combination does not necessarily produce change, it does not differ in this respect from what is usually called molecular combination. The lecturer then referred to an important difference in the adicity of chlorine and oxygen. Chlorine can combine with methyl or ethyl singly.
Men have from time immemorial put things "in their bellies to steal their brains away." The chemical substance known as ethyl alcohol has been an artificial basis of good fellowship the world over, as well as furnishing a very fair share of the tragedy, the misery and the humor of the world.
"Just a moment, Miss Dodge," he encouraged as he jabbed the needle into her arm. She did not wince. "Please lie back on the couch," he directed. Then turning to us he added, "It takes some time for this to work. Our criminal got over that fact and prevented an outcry by using ethyl chloride first. Let me reconstruct the scene." As we watched Elaine going under slowly, Craig talked.
"Of course no attempt to identify these oils in the quantity sent, viz., 632 c.c. The ethers are returned as ethyl acetate, but from fractional distillation amyl acetate was found to be present. In a subsequent letter Mr.
