In this video, I prepare copper phthalocyanine, a dark blue copper-containing organic compound used commonly as a pigment for coloring paints and plastics.
wow! nicely done. Will try this myself!
cool, cant wait for more of this
I am going to attempt this reaction this weekend. But I will be using boric acid as the catalyst.
When you snap a glass rod, keep the longer pieces.
The broken end has nice flat sharp edges, perfect for getting stubborn gunk off the bottom of a cruicible.
Too few videos on your channel, Do something.
Haha, I plan to do something about that soon. I recently moved into a dorm room though, so my opportunities to do chemistry have been limited to weekends that I'm able to go home.
@Texium Nice man! Im looking forward to it! Are you studying chemistry then? :D
Of course!
Wow! Amazing to see how the pigments in our daily used watercolor is actually made! And you made it so clear! Love it!! Too often we find bragging, or ads, instead of knowledge! This is real sharing! Thank you!
which pigment have thermochromic property
I've been fooling around with Graphene super-capacitors based on Robert Murray-Smith's YouTube channel, one of the things 'n picked up is the use of "Deep eutectic solvents" and Ionic Liquids. Not going in to deep into something I do not consider myself an expert in, the short is Urea (Ethylene Glycol also) likes to complex with metal Halide salts, forming an Ionic liquid. (Side not, oddly it is that exact same complexing between Urea and Copper Ions that is the reason for the bright colour of the resulting compound you're synthesizing) So what happens is the two powders complex with each other forming an almost oily viscous liquid. I would think that you would need a stoichiometric ration op Copper salt to Urea for your reaction thus "dissolving" all the powder, but seeing as you end up with a past like consistency I am not entirely sure what are all the possible causes at play here, again, I am by no means an expert in this, just something I have seen happen and done myself a bit. Hope this little insight was at least somewhat interesting.
PS: Something I just thought of, the complexing between Urea and the Copper (II) Chloride might release water as it a hydrated salt, adding to the paste like consistency, maybe the complex might not even be a liquid at room temperature, as I know not all of them are (those that are not are call Ionic Melts I think)
Copper Phthoalocyanine may seem really easy to make, and it is, but do be wary that it stains everything. It's known to be really difficult to remove once it stains. It's not necessarily dangerous (relatively, although it is a high heat process), but it is extremely messy.

Cant wait for more! I find this so interesting, but there are so few channels left (that I know of) that can get this form of content right, good job man!
