polarity of diethyl ether

EXTRACTIONS: What if methylene chloride was used as the

I've already done the lab where we had to separate an unknown mixture of an acidic basic and neutral component in a 1:1:1 As for my answer I would think nothing would be 'drastically' different because methylene chloride is an organic solvent that is immiscible with water but miscible with many organic solvents However in lab we used diethyl ether in lab and I know that its slightly

A robust and efficient method for the extraction of plant

The hexanes:diethyl ether (90:10) solvent system was chosen for this testing based on its slightly higher polarity (compare dielectric constants Fig 1) and therefore its potential ability to extract amphipathic compounds (e g aldehydes fatty acids) To optimize the time of extraction for fresh silks from maize inbred B73 duration of
