So glad to be here as a new member
I have been hanging out in the forum for almost 2 years now, from just having chemistry as a hobby to studying it full-time, this page has always been
my go to inspiration for any new ideas to test in the lab. I had transformed a room in my parents' house into a lab with the sink being the adjacent
toilet room. Although there are sufficient equipment for things like distillation or a small natural product synthesis or extraction, I lack the time
to do many of them. So I would really appreciate any suggestion from the experienced ones about things I should do with my beginning-to-collect-dust
lab.
Here are a few of the things I have done so far:
1.Cinnamon essential oil distillation (this one seasoned my entire house with cinnamon)
2.Glucosamine extraction from prawn shells
3,4.KDP and copper sulfate crystal
My mother tongue is not English so I hope you guys would help to correct me if I'm wrong and I look forward to talk more with people on Sciencemadness

Welcome
2.Glucosamine extraction from prawn shells
This is a project I would greatly appreciate if you where to share !

Welp, I would say the project wasn't a success or anything but I can give you the research that I based on to do it and a few tips if you aren't
familiar with this kind of extraction/synthesis.
Research
There are a few required equipment and reagent that are necessary for this such as the jacketed condenser for refluxing, a reliable vacuum filter set
up, sodium hydroxide, hydrochloric acid, the purest ethanol you have.
(Note: the setup in the image above is an quick fix solution for not having a condenser, which resulted in the suck-back that ended the final reaction
early)
The process that I did skipped a few steps like depigmentation or recrystallization of the product. Some tips that I have concluded from doing this
extraction:
-Use "a lot of" starting material, which is the shrimp shells
-If you source the shells from food waste then there should be a step where the shells are boiled thoroughly for a least 30 minutes. In this step I
had to manually scrapped off the remaining meat sticking on the shells, maybe it will be less tedious if you boil it longer.
-The smell of the product from the final hydrolysis in HCl in my experience is kind of sweet.
That's all! I hope that if you give this project a try the tips I give you here will help a bit in the process and I will look forward to anyone who
can share their experience in this subject or similar projects.

Thanks, Next time I get time will try, have easy access to shells! Time how ever is all ways found wanting.
