Do you know if carrot juices require saponification, too? Do you extract beta-caroten from fruit juices only by centrifugation without saponification?

after the saponification step, my solution turn solid, forming like a gel, when cooled. what may had happen?
@MicroChemsExperiments2 жыл бұрын
If you face to form gel in the separation funnel then it is called emulsion. To remove emulsion, add ethanol and shake again

I used petroleum ether for extraction. I got separate layer bt by washing ethanol and distilled water It did not separate what can I do.
@MicroChemsExperiments2 жыл бұрын
Ethanol is fully miscible with water. So you will not found separate layer between ethanol and water. During this test, ethanol will be discarded along with the water. Just collect the hexane layer after washing.

while performing experiment everytime emulsion is formed in which step am doing mistake pls Guide

Please add extra ethanol to the emulsion and shake. The emulsion will be cleared out

After 14th wash no clear layer formed at top what will be the reason ?
@MicroChemsExperiments Жыл бұрын
Loss of hexan with emulsion during washing the extract. Wash it more carefully

According to IS 548, nowhere they have used hexane. Why is this video using hexane?
@MicroChemsExperiments Жыл бұрын
Petroleum ether and hexane are very similar in chemical properties. You can use both

Alamin Lemon, we used commercial standard 0.1N NOH solution (ready made) in this test, that's why we didn't standardize our solution. In future, we will make video of a procedure for standardize different solutions including sodium hydroxide.
