Default a quick question

i know there are several threads on this but i dont feel like digging up the past for a quck question about NG

for making nitroglycerine---

how much nitric acid of 70% concentration do you use with sulfuric acid 98% concentration to glycerine?

so :

(x)ml of nitric acid 70% to (Y)ml amount of sulfuric acid 98% to (Z) amount of glycerine ------> (W)Ml nitroglycerin
( fill in values w,x,y,z)

this must sound like im trying to get spoonfed, but evrywhere i look on google it always says 100% nitric acid, which i dont have and if i do the math i feel like there is somekind of necessary ratio to stand with and i will mess that up and end up dying.

Old book say: One part of glycerin is nitrated with about six parts of mixed acid, made up with oleum, containing about 40% nitric, 59.5% sulfuric (oleum, strong as fuck sulfuric acid containing free sulfur trioxide) and .5% water. I made a thread wondering about an oleum setup but the glitch ate it. Honestly, i don't really think precision matters too much in the mixture, as long as there is a small excess of acid and you watch your temps like a mutha..
Not enough acid and you will get some inferior glycerin DI-nitrate in the product, too much and you will waste good chems. You probably will not bother making oleum, so just use a bit more (idk, 8? 10%? ask X-ray.) concentrated sulfuric acid. Personally, i have a bit of a thing for nitroglycol, seems to be just better in most respects than nitroglycerin, except for two things: Its about 150 times more volatile, in the sense that it evaporates way easier, and is more soluble in water, meaning you wash away a tiny bit of product when you neutralize it, but not much, esp. if you use cold water. Other than that i would say its superior in every way to nitroglycerin. ...And its a bit stronger.

..and thats by weight, not volume i'm almost sure!!

There are actually charts out there that give information about nitrating mixtures and their concentrations for making nitrate esters. I had an excell file with graphs in it for PETN synths in which you could fill in your concentrations and quanitities and it would calculate all the other variables for you. I actually still have it on a harddrive here but it should also be somewhere free on the web. With varying concentrations of nitric and sulfuric, different reactions tend to be favored that will or will not end up with the desired product. These reactions can be manipulated when for instance if you happen to have a nitric acid of low concentration you can nitrate via sulfonation if I remember correctly, meaning you'll have to add a lot of sulfuric acid. Not to mention that all these reactions are occuring like constantly changing equilibriums (for instance, once your product starts to form, your nitric concentration in your mix will go down changing the reactions that are occuring). Does anyone understand what I just wrote?? does it make any sense at all?? I just type sprayed it out like a bad case of cholera.. this is kinda what my mind looks like on the inside, lol. peace.
