Product of an acetylation. Hard to believe, but only less than 1% of byproduct causes the black coloration on the white crystals. Just a quick wash with methanol and white crystals will be obtained.

What is acetylation? Making an acetyl ester of an alcohol, in this case with acetic anhydride.

How does this looks? Here is an example with acetylsalicylic acid (Aspirin): 

Ferrocene

Synthesizing, acetylating and separating using column chromatography was actually very interesting. Remaking the point in history when the first “sandwich” compound was discovered in 1951, a very cool structure to a molecule that has proven itself to be very useful through the ages.

Hey Sahar,  First thing~ Thanks for all you’re amazing feedback and “keeping it real.”  It’s so hard to find people these days who are honest with people about weight loss and fitness. You’re amazing!!! :) I am trying to lose belly fat and typically do my cardio in the morning. Should I be doing fasted cardio to help with losing fat or not? Also, do you have any other tips to help speed up the process?  Thanks again!!!  XXOO

aw thank you so much, I appreciate your kind words :)

fasted cardio definitely helps with fat loss as its using both glycogen and fat for fuel and if you haven’t eaten anything then you will be burning of fat storage. For optimum results I would recommend taking a scoop of Acetyl L carnetine before cardio (helps shuttle all of the fatty acids stored to be used as fuel).

HIIT cardio is also good for fat loss, I wouldn’t do that fasted though as with a bit of food in the system you can smash it out much more efficiently. This burns fat and increases endurance whilst retaining muscle. 
Stomach fat is always the last place to go so just be consistent in training and especially diet, watch your portion size and try full up with lean proteins rather than energy dense processed foods :) 

Good luck gorgeous! xxx

hey babe! quick question. so im trying to lose weight and im eating very well, doing cardio and weights. I weight train 'like a guy' ie, 12reps x 3 sets doing the highest weights i can do. How likely is it that I will bulk up? like will i build noticeably bigger muscle before i lose noticeable fat?

heyy!
I can’t really answer what you’ll notice first; they will usually go hand in hand but eating a healthy diet will be what will help with fat loss and ensuring you’re getting enough fuel for muscle development paired up with heavy weight training.  So keep eating well, lift heavy and you’ll definitely notice an increase of lean muscle development and a decrease in fat mass. You can also take these supplements which will help: Acetyl L Carnetine and CLA capsules (particularly good in increasing the lean muscle mass/fat mass ratio). Also if you incorporate a few HIIT sessions of cardio that will help with fat loss whilst still retaining muscle mass as opposed to LISS cardio. xx
