Organic Chemistry students synthesized aspirin to practice organic synthesis with compounds containing benzene from Friday, Oct. 10th to Monday Oct. 20th.
Students began the four-class-long lab by combining salicylic acid, acetic anhydride and sulfuric acid to produce acetylsalicylic acid, also known as aspirin. They proceeded to vacuum filter, purify and confirm the identity of their compound.
Organic Chemistry student Spencer Mo (11) notes the lab provides hands-on experience working directly with lab equipment and reinforces lab safety.
“This is our first major experiment of the year and it’s definitely quite interesting because we’re getting used to lab materials,” Spencer said. “Right now we’re learning about the aromatic ring molecule type synthesis, and it’s in the same vein as the lab we’re doing because aspirin is also based on an aromatic ring.”
Organic Chemistry teacher Jane Prosek Gorninski hopes that the students become more confident in their abilities, whether it be mastering new techniques like handling strong acids or learning how to follow complex procedures.
“The first thing they ask an organic scientist is to know how to do a synthesis,” Gorninski said. “Safety is something that we have to be very aware of before we do things like this. You can never do it without a person that is experienced in case something happens to mitigate any problem.”
While the four-class procedure may seem long to some, Organic Chemistry student Leo Zhang (11) believes that the extended process is a valuable lab experience.
“I don’t know if any of the teachers ever offered a lab that it takes almost two weeks of classes to accomplish — it’s very in-depth,” Leo said. “We do a ton of work from just starting from the raw materials to hopefully in the end, synthesizing commercial aspirin with an acceptable degree of purity. It’s great practice [using] all of the organic chemistry lab techniques we’ve learned so far.”
Organic Chemistry student Aya Sugaya (12) feels as though this first major lab cements her interest in chemistry and presents a better sense of what college science classes would look like.
“I’ve enjoyed my chemistry classes so far,” Aya said. “I’m also thinking of doing something like chemistry or biology in college. [Organic chemistry] is notorious for being that really difficult course, so I wanted to try it out, see how it goes [and] prepare myself for college.”

















![“[Building nerf blasters] became this outlet of creativity for me that hasn't been matched by anything else. The process [of] making a build complete to your desire is such a painstakingly difficult process, but I've had to learn from [the skills needed from] soldering to proper painting. There's so many different options for everything, if you think about it, it exists. The best part is [that] if it doesn't exist, you can build it yourself," Ishaan Parate said.](https://harkeraquila.com/wp-content/uploads/2022/08/DSC_8149-900x604.jpg)

I know that there's a lot of people that are really confident in what they do, and I really admire them.
