Science - Chemistry; Chem Sci/Eng / cleaning products (again!) | | French term or phrase: 1-alky-amido-3-diméthylammonio-propano-3-carboxy-méthyl- bétaïne | Ce constituant est également désigné sous le terme « cocamido-propylbétaïne ». Il répond à la formule suivante :
CH3
R-CONH-(CH2)n-N+-CH2-COO-
CH3
avec R = chaînes de 7 à 17 atomes de carbone.
I'm afraid much of the formatting of the formula was lost before it ever reached me.

| | Clarification request(s) and responseZareh Darakjian Ph.D.: 4:02pm Jan 8, 2005: Hi Gabrielle:
Do you know what n is? It seems to me odd to have 3-dimethylammonio here. The only dimethyl we see is on he left. Thoses are not attached to ammonia! -
Zareh Darakjian Ph.D.: 4:03pm Jan 8, 2005: I also don't see how it could be 3-ammonio if we don't know what n is. If n is 5 or 6 or 7 I would think
the 3 will change accordingly! -
Gabrielle Lyons (asker): 5:40pm Jan 8, 2005: There is a definition of n from a couple of pages earlier. I don't think it has any connection, but here it is anyway:
"These constituents, which can also be referred to as sodium alpha-olefin sulphonates, are mixtures:
of:
sodium 3-alkene sulphonate CH3-(CH2)n-CH = CH-CH2-SO3Na;
and of: sodium 3-hydroxy alkane sulphonate CH3-(CH2)n-CH-CH2-CH2-SO3Na l OH
[The l is a vertical line down to OH on the line below.] In which n corresponds to a number between 10 and 20 inclusive.
Original French is:
Ces constituants, qui peuvent également être désignés comme étant des alpha-oléfines sulfonates de sodium, sont des mélanges :
de : et de :
3-alcène-sulfonate de sodium 3-hydroxy-alcane-sulfonate de sodium
CH3-(CH2)n-CH = CH-CH2-SO3Na ; CH3-(CH2)n-CH-CH2-CH2-SO3Na
l
OH
dans lesquels n correspond à un nombre compris entre 10 et 20 inclus.
I'm counting on you, Zareh! I have only school chemistry. The agent said it might 'contain a few simple chemical terms'...
Zareh Darakjian Ph.D.: 6:41pm Jan 8, 2005: Hi Gabrielle: I just talked to an organic chemist graduate student here.. She and I agree that the formula
does not correspond to the name (the question you have) Probably the name is correct... So if we want the name in English, I have given the answer. -
Zareh Darakjian Ph.D.: 6:42pm Jan 8, 2005: Hi Gabrielle:
I don't think the client expects you to fix the FORMULA. The client is interested in naming the compound which you have in the source. I have the answer below. -
Zareh Darakjian Ph.D.: 6:43pm Jan 8, 2005: I noticed a typo in the queston.
It's not alky it is alkyL -
David Sirett: 7:05pm Jan 8, 2005: The two CH3 groups are bonded to the N+ towards the right-hand end, the "betaine" part of the molecule: R-CO-NH-(CH2)n-N+((CH3)2)-CH2-COO-. IMO the "propano" bit is valid only for n = 3. Betine on its own is ((CH3)3)N+CH2COO-. -
Zareh Darakjian Ph.D.: 7:09pm Jan 8, 2005: Thank you David. I am assuming that we are not expected to fix the formula!
The forumla is wrong! if the source term is right. -
Zareh Darakjian Ph.D.: 4:08pm Jan 9, 2005: Glad to be of help, when I can, Gabrielle! -

| | 1-alkyl-amido-3-dimethylammonio-propano-3-carboxy-methyl-betaine | Explanation:
If the source is correct, then this should be the answer.
notice that it is not a butane, it is a betaine... a very different animal.
I will do some review of my betaine nomenclature... and see if I can give more info.
but f the source is as it is, then this probably is the translation...

In looking again, I would remove the \"-\" between carboxy and methyl
In English we don\'t have carboxy-methyl. We have
carboxymethyl
Also I would remove the \"-\" between alkyl and amido.
In English it is alkylamido
like methylamido
