I would completely drop / change the first paragraph. I sense that talking about monetary motivation (even when you are not after it) in any way when you're going to be paid like shit for 5-8 years is a terrible idea.
I would not use the word "things" in an official piece like this
Air free synthesis.... Not uncommon in undergrad. Everyone knows how to use a glovebox if they've worked a summer.
I would make the first part of your essay more personal after all this is when you made the (bad by the way) decision to go to gradschool because you fell in love with chemistry. Not by using more flashy adjectives but by describing something in more detail. I have no idea what reactions you did and what the challenges were, if you optimized etc. For all the admissions knows you've just replicated someone else's notebooks and compared your data.
Same goes for the biotech industry. Chemical biology is a bunch of kits with instructions where if it works it works and you're lucky, if it fails..god why? Details of optimizations or anything. something specific that started your interest then just bunch all the kit business in one sentence and move on.
If the company you work for is the fastest growing i'd bet universities know already. get rid of that sentence it says nothing about you.
Don't end sentences in prepositions "like." it's still a thing after college to not do that
There's too many words dedicated to techniques or bond dissociation energies or really things that belong in a notebook not a personal statement that explains your motivation. Running hplc is not what is bringing you to gradschool.
Also i assume you know but all graduate schools will want you to teach. You may want to do industry but if you don't say anything about any teaching love that may be a minus...
Good luck
