Carbamate and carbonate salts of tertiary amines

DETAILED DESCRIPTION Illustrative of the novel carbamate compounds of the invention, although not limited thereto, are the following, prepared by reaction of a secondary and tertiary amine with CO.
sub.
2 : ##STR5## prepared by reaction of CO.
sub.
2 with dibutyl amine and ethyldimethyl amine; ##STR6## from diethanolamine and N-methyl morpholine; ##STR7## from dimethyl amine and triethylamine diamine (TEDA); ##STR8## from morpholine and dimethyl ethanolamine; ##STR9## from diethanolamine and bis (N,N'-dimethylamino)-ethyl ether.
Illustrative examples of the novel carbonate compounds of this invention, although not limited thereto, are the following in which water, carbon dioxide and a tertiary amine are reacted as indicated below: ##STR10## EXAMPLE 1 Into a round bottomed flask there was charged 400 parts by weight of diethylene glycol solvent, 105 parts of diethanol amine and 112 parts of triethylenediamine (equimolar parts of reactants).
The mixture was stirred until complete solution was obtained.
A CO.
sub.
2 generating device (dry ice in an Erlenmeyer flask) was then connected to the stirring reaction mixture and CO.
sub.
2 allowed to bubble in for one day under pressure of 200 ml of water.
At the end of this period the flask containing the reaction mixture was weighed and a weight gain of 36 parts was noted, due to the reacted CO.

The product was analyzed by nuclear magnetic resonance (NMR) spectroscopy.
The NMR analysis showed the product of Example 1 to contain the carbamic acid salt of triethylenediamine and diethylene glycol.
The analysis as shown in Table I was carried out at .
