Is it possible to use a slightly lower concentration of HCl in reaction without a huge hit to yield? like so instead of 70% i'll get 60% and not something like instead of 70% i get 5%
Possible to replace 35-38% HCl with 30%?

Hello, we have to guess which reaction do you mean?

Sorry, my bad. In the bromination of 4mmc
3. Hydrochloric acid (HCl 36% aq) 50 mL is added into the reaction mixture. It is the catalyst of bromination reaction. A weak stirring is turned on and bromine addition is started.
4. The first portion of bromine ~50 ml is added. The solution is turned brown and eventually is discolored. It means that the bromination reaction is taken place. You have to wait this moment, and not pour out all bromine in a one portion to avoid a violent exothermic reaction with a subsequent boiling off of the solution.
5. Bromine is added from the drip funnel to the solution dropwise, when the first Br2 portion is discolored, in order to a smooth reaction course. If the solution begins to boil, the addition of bromine have to be stopped until the solution is cooled to 30-35 ºC
This part, also do you know of any good places to find reagents? thank you!

You can use 30%, but you have to take more. Recount dry amount of HCl in acid. For example, you'll take 50 ml 36% = 18 ml of acid, hence, you have to take 60 ml 30%. "Science, bitch" (c)
