Yeah, I think this is just an error. These brochures are usually put together by people who don’t have a chemistry background.

It’s not particularly effective.

@Paul - We are doing a free webinar on the subject through the IFSCC tomorrow. Register here.

What system are you posting from (mobile device, laptop computer or other)?

@Pharma - Still trying to figure this all out. To cite a previous post, I think you just have to paste in the link to that post?

I’m trying to fix the site but one trick you can do is to use Google.
Go to Google. In the search bar type chemistscorner.com : <username>
I think that will show all instances of that person’s posts. But the link might not be quite right. If the link to any of them has the format https://chemistscorner.com/forum/discussion/xxxx Remove the /forum/ part and try it without that. That should call up the right page.

Thank you for attending! Especially, at such a late/early hour.
If you want to watch a replay you can see it here.

I’m working on figuring out how to change from “member” to something else.
However, in the “profile” section you can put a lot more than in the previous software. I’d suggest you populate that so anyone who clicks on your username will get the information they need.

I’m not sure I understand the problem with the search function. Is it working for you now?
I tested it on my system and it is now working. It could be a “cookie” issue on your computer at the moment. Perhaps clear cookies and try.
Let me know if you are still having problems.
Thanks!

I still have the old database so all the info from the forum is still captured. It’s just a matter of setting it up to work with this new software. At the very least I can turn the old stuff into a PDF.

No data should be lost, so it is still in our database. I will have to check with my IT guy on where those might be.

See my edited previous comment. The calculation is in the last paragraph.

I asked ChatGPT and it said…
“The molecular weight of cetearyl alcohol is 392.62 g/mol.“
I don’t think that is correct either.
More from ChatGPT -
“The sum of the molecular weights of cetyl alcohol (C16H32O) and stearyl alcohol (C18H38O) is approximately 410 g/mol.
To calculate this, we first need to determine the atomic weight of each element in the molecule and then multiply it by the number of atoms of that element in the molecule. The atomic weights of carbon (C), hydrogen (H), and oxygen (O) can be taken from the periodic table.
For cetyl alcohol, the molecular weight is:
16 (C) * 12.01 (atomic weight of C) + 32 (H) * 1.01 (atomic weight of H) + 1 (O) * 16 (atomic weight of O) = 192.48 g/mol
For stearyl alcohol, the molecular weight is:
18 (C) * 12.01 (atomic weight of C) + 38 (H) * 1.01 (atomic weight of H) + 1 (O) * 16 (atomic weight of O) = 218.36 g/mol
Finally, the sum of the molecular weights of cetyl alcohol and stearyl alcohol is:
192.48 + 218.36 = 410.84 g/mol
Note: This is an approximate value, and the actual molecular weight of cetearyl alcohol may slightly vary depending on its specific composition.“
So, I think the average molecular weight is (x)192.48 + (y)(218.36)
In this case x = fraction of cetyl alcohol and y = fraction of stearyl alcohol -
Ok, I’ve figured out how to allow media and emojis.
This is a wysiwyg editor so if you want to underline something you can highlight it and do <ctrl>U
<ctrl>B bolds text
<ctrl>I italicizes, etc. -
Yes, this will be recorded. If you sign up you will be alerted when the replay is ready.
