GLYPHOSATE ISOPROPYLAMINE SALT
« on: September 23, 2010, 12:15:22 PM »
Hi,

I wonder how to "extract" isopropylamine and glyphosate (alone) from Roundup , it's water solution of glyphosate isopropylamine salt. Help

Nice first post...

When making a new thread in Drug Synthesis & Extraction, Other Chemistry, and Pharmacology - and preferably others if applicable show that you have researched, and have searched here on the site by providing links and references of relevant information, or at least mention how you cannot find any detail related to the subject in which you are posting.

Is the link to the rules to hard to find?

You can still add and edit your first post I believe -- if not, do it in a new post.
maybe look into hydrolysis, acid/base reactions, previous conversations, etc.

An Identical post was made at the wd site by this person.  should we be putting product names in these forums? IMHO it leads to additives to prevent their use and doesnt add to the chemistry.

All that we see or seem is but a dream within a dream...

ok here we go : show that you have researched ??? how can i show that ? is this forum for asking question , i didn't find any relase topic in whole net , in this forum is nothing about isopropylamine, glyphosate or any pesticide (SAFE !!! glyphosate is perfectly safe), how cannot i find any detail ?? wow this question is really funny , because i can't and that's it also beacuse there is NOT ANY HELPFULL INFORMATION, if there is some advise to this i would't posted here, some talk about acid/base i think this doesn't work or should we extracted with ether amine or evaporate i DON'T KNOW !!!!!!!!!!!!!!!!!!!!!!!!!! putting product names in form ? WTF ?? my brain could not understand that , i see post in here is very unwelcome , i post in other forum that more people could help me and show some knowledge , now i see this is wrong idea

First off, I would like to say that it sounds like there is a language barrier - so that can explain some of the confusions, issues, etc. However - typing in caps and adding twenty exclamation marks is not polite, regardless.

by providing links and references of relevant information, or at least mention how you cannot find any detail related to the subject in which you are posting. You did not do this in your first post - you simple asked to be "spoon fed"

For instance.. maybe you could have mentioned the idea of hydrolysis? What issues you think you might run into - Perhaps you think it might decompose the glyphosate if a strong base is used, and you are unsure of how to extract the formed isopropylamine salts if an acid were to be used.  Perhaps you know how to separate the isopropylamine from the glyphosate but are unsure of the surfactants found in said herbicide.

We do not know what issues you are or were having with this reaction - but at the assumption of you having english your second language, and being new to the scene - I will be nice and help point you in the right direction.

The main active ingredient of Roundup is the isopropylamine salt of glyphosate.
-- wiki

Isopropylamine, also called 2-aminopropane, 2-propanamine, monoisopropylamine, and MIPA, is an organic compound, an amine. It is a base, as typical for amines.It is a hygroscopic colorless liquid with ammonia odor.

Glyphosate is an aminophosphonic analogue of the natural amino acid glycine, and the name is a contraction of gly(cine)  phos(phon)ate.

Glyphosate goes by the names N-(phosphonomethyl)glycine (the IUPAC name)
and the other name of  2-[(phosphonomethyl)amino]acetic acid

Amides are commonly formed via reactions of a carboxylic acid with an amine.
-- http://en.wikipedia.org/wiki/Amide#Amide_synthesis

Perhaps the herbicide is an amide?

Quote
They can be hydrolysed in hot alkali, as well as in strong acidic conditions. Acidic conditions yield the carboxylic acid and the ammonium ion while basic hydrolysis yield the carboxylate ion and ammonia.
-- http://en.wikipedia.org/wiki/Amide#Amide_reactions


Isopropylamine is a base because of its amine functional group. If it is forming a salt with glyphosate, which is a carboxylic acid, as its name tells -  it would seem to suggest that it is an amide of some sort, and with most amides and other salts of amines or carboxylic acids.. adding a strong acid or base will release one of them accordingly, and form another salt with the other one.


additionally I was being nice to you in NOT closing your thread, and ALLOWING you to add more info and research to it.
It is much more than what happened at your copy&paste post:

ok Sir , i have idea .... i read about reductive amination of ketones , we take for example 80 parts NH3 20 - 25% and 15 parts acetone , now i have a question ... reduction will be work with nickiel sulfate and zinc but i read that Al/hg will works too , so how many al foil i should take to reduce it , and second question if the reaction will be complete should i add conc. NaOH solution to freebase isopropylamine ? or extract with ether ? or evaporate ? i hope you will help me

chemistry is trial and error, and often it has many many different methods to get to the same place.
First off - now you are on a different topic - the reductive amination of acetone with ammonia.. vs the herbicide.  - Al/Hg is probably better than the NiSO4/Al since I have never heard of that. Look on SMBD for info on the reductive amination of acetone.. I'm sure it is at least vaguely mentioned there.

Just dry up the herbicide and add a base to liberate the isopropylamine or something like that - you just need to try it to know for sure.
