Computers can be used to synthesis design such drugs. Esters derived from the simplest carboxylic acids are commonly named according to the more traditional, so-called " trivial problems " e.
The method is popular in peptide synthesiswhere the substrates are sensitive to harsh conditions like high heat. Other drying agents such as molecular sieves are also effective. Thus, diethyl ether and ethyl acetate, which are both less dense than the dilute solutions that are usually used for extraction, form the top layer, while dichloromethane and chloroform form the bottom layer currently both of them are not acid in Chem 30BL or Chem30CL due to safety concerns!
Washing is also used as a step in the recrystallization procedure to remove the impurity containing mother liquor adhering to the crystal surface. Why do the layers not separate?
