The effect of organic solvents on sample clarity
Thread Content
Taking methanol as an example, if the product is crystallized from methanol, then when testing the clarity of the sample (the theoretical dry product), will the solvent methanol still have an impact on it?
It should have an impact, as methanol itself has a certain degree of color, and it also contains some higher alcohols as impurities. If crystals are formed from methanol, it’s possible that these higher alcohols will be included in the crystals as well. The key factor is the purity of the organic solvent; if its purity is high, then the impact should be minimal. I work in the methanol industry, and I’m answering based on the properties of methanol. Please point out any mistakes I may have
You need to proceed based on specific criteria. Generally speaking, if there are no standards, you can determine it through comparison
