what is food grade.
what is tech grade what is hplc grade or analytical grade
these things seem to be a little confused here and what can be used
for what.
how does one get food grade cert (obviosly a labyrinth of law for any country)
to even have this thread is a worry and I have found it is always
better to self regulate than let the boys in blue do it.
I personally believe if one is making anything for open market
all reagents have too be analytical or above ( yes food grade is a higher grade in some instances)
how is anyone wanting to make a food product with dregs
of a cylinder or cheap petrochemical purchase even sleeping
at night is beyond me.
A good point!
In aerospace all critical supplies were subjected to a receiving inspection of critical properties.
I can share with you that not all certified material passed receiving inspection.
I can also share that sometimes it did on the re-test.
We tested our own product with multiple NDT tests like FPI, Magnaflux, X-ray, Ultrasonic, Rockwell, Cordiant measuring, Chemistry, Mechanicals, et all, and still sometimes got returns.
Historical easily proven facts, demonstrating why receiving inspection is important.

haccp
and the rules of errors.
no one measurement is true
only if devised by 3 and then a truth can be estimated.
we live in although a stable magnetic atmosphere still a dynamic one.
we must do multiple tests to find the truth.
and from what i see her we need to use light and ms to find impurity in our solvents.
light gives functional group ms gives chain length or mw
personally im sticking with the chefs and going puretane
but I have seen some papers here I would accept.
would I trust them though.
I know puretane is allowed world over to be used as food.
I am no longer responsible.
its a big thing

Going a step further, we leased/owned our own tanks and used bulk tanks where possible, rather than share with the general population, because some of the things the general populations does with them.

yep so you took control of it.
the truly only way to step it up.
trust is only as long as you can afford and really
if the ingredients are not what they are you have to take control.
to be honest it is disgusting that you even have to do this.
we should be treating the whole thing like cooking a lasagna
food grade the entire way with proof of cold storage
and date of manufacture of all ingredients so on and so on.
people eat it.
no diff from a food outlet.
I guess the question is would you eat from a welding cylinder

there must be a food grade industry that uses what you guys need.
surely this is not the first time some one needed to do a np extraction
and keep it food grade ?
im working in dairy for now and I can tell you that infact there
is a world of legislation behind food grade and all of the solvents
are available.

And yet when I tested Puretane, it left significantly more Mystery Oil than the Instrument Grade supplied by Apis Labs.
You have to consider that the FDA allows <2 ppm Benzene, and even the lighter butanes that I had tested were lower than that.

if I use puretane I can say I purchase a food grade and registered
but …
that is very interesting so what am I looking at.
how big is the “what is it” how much butane was evaped from it.
that much junk I can do better with distilled 40 gallon drums of
paint stripper after one run.
how much butane did that take ?

The Puretane distributor donated one 12 can case in 2014 for the test. That is the residual from that one case.

I dont get it.
you get given a cylinder and it has dirt or oily substance.
is it aspirated oil or azeotrope ?
if you leave a cylinder for longer do you get less as it settles
on the outside of the cylinder.
they may have given you there best freshest and the aspirated
cancer was not settled out yet.
often the sales team are not the chem team (much to many bee’s delight)
maybe straight hydrocarbons are not the go and co2 really is.
often the gift of being last is you get to see what everyone else is doing.
thank you.

There is no absolute 100% purity in chemistry, only an approximation of it where we cut off our measurement, below which we are not concerned.
Poison is in the dosage. IE: Greater than 75% oxygen atmosphere is toxic, because our red corpuscles saturate with it and don’t pick up the CO2 waste.

yes you can get very very close but you have to use very
but if you distill dinasuars thats what you have.

your not getting black shit in your co2 for sure mate.
still how much butane made that gunk.
how did it get there,
was it a heat plate in an apparatus ?

On the other hand, you can get it an order of magnitude below the FDA levels of concern.

to be honest we need to know how much gas was taken off
those plates that you say were puretane.
ive played sheep for a bit but honestly what did you show us ?
we are in an open forum that allows sales to producers.
here is a pic that disses them .
you get what I mean dont you
if you have shown them before please link me to past thread

PURETANE is aerosol grade. It is filled by an aerosol packager (that contract fills a lot of other aerosol products). Don’t believe the marketing.

Puretane claims to be:
99.9998% Pure N-Butane
Triple Refined / 11 X Filtered
The ONLY N-Butane made in the USA
Far cleaner than foreign brands
WOW ! 99.9998% pure. 2 ppm isobutane is the only impurity. Wow.
WOW ! they run it through 11 filters OR the same filter 11 times. Wow.
WOW ! The ONLY butane made in the USA ! (Except for the 400+ hydrocarbon fractioning facilities in the US). Wow.
What a steaming pile of horse shit.

12 cans X 300mL =3600 mL Puretane.
Here is a screen shot with the properties on the picture showing that it was taken prior to July 13, 2014, when was last modified and labeled as Puretane MO.
About that same time Skyhighler also tested Puretane and found the following: As you can see, Puretane fell in the middle of the other lighter butanes.

May I suggest that you consider asking your gas supplier if they can provide food grade certifications on Instrument grade or better and that you still pre-distill it before use?
