- the present invention pertains to a method for the alkylation of amines.
- N, N, N', N”, N”-pentamethyldiethylenetriamine is used in the formation of rigid foam polyurethane.
- Current technology for PMDTA production relies on the methylation of diethylenetriamine (DETA) in the presence of hydrogen by using formaldehyde as methyl source. This methodology is selective towards PMDTA.
- formaldehyde CMR compound raises HSE concerns.
- US Patent No. 5105013 teaches a process for the preparation of permethylated amines, particularly pentamethyldiethylenetriamine, by the reductive methylation of diethylenetriamine in the presence of hydrogen, formaldehyde aqueous solution, a catalyst, and a solvent. The reaction was carried out in two reaction phases and the flow rate of formaldehyde must be well controlled.
- the present invention therefore pertains to a method for preparing a compound having general formula (I) by reacting a compound having general formula (II) with an alcohol having general formula (III) in the presence of hydrogen and a metal catalyst:
- - R is an alkyl, alkenyl or alkynyl
- - n is an integer between 0 and 20
- - m is an integer between 1 and 3

- Fig. 5 is an image of concentration (DETA in methanol) -yield curve of reaction of DETA with methanol over Pricat Cu 60/8P of Example 7.
- Ratios, concentrations, amounts, and other numerical data may be presented herein in a range format. It is to be understood that such a range format is used merely for convenience and brevity and should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also all the individual numerical values or sub-ranges encompassed within that range as if each numerical value or sub-range is explicitly recited.
- the compound having general formula (II) is a compound having general formula (IV) :
- n is an integer between 0 and 20, preferably between 0 and 9, and more preferably between 0 and 4.

Abstract
The present invention pertains to a method for the alkylation of amines. In particular, the present invention relates to a method for preparing N, N, N', N", N"-pentamethyldiethylenetriamine by reacting diethylenetriamine with methanol in the presence of hydrogen and a metal catalyst.
Description
The present invention pertains to a method for the alkylation of amines.
N, N, N', N”, N”-pentamethyldiethylenetriamine (PMDTA) is used in the formation of rigid foam polyurethane. Current technology for PMDTA production relies on the methylation of diethylenetriamine (DETA) in the presence of hydrogen by using formaldehyde as methyl source. This methodology is selective towards PMDTA. However, the use of formaldehyde (CMR compound) raises HSE concerns.
For example, US Patent No. 5105013 teaches a process for the preparation of permethylated amines, particularly pentamethyldiethylenetriamine, by the reductive methylation of diethylenetriamine in the presence of hydrogen, formaldehyde aqueous solution, a catalyst, and a solvent. The reaction was carried out in two reaction phases and the flow rate of formaldehyde must be well controlled.
Hence, there is still a need to develop an environmentally friendly process to prepare PMDTA in high yield and selectivity, which can overcome the drawbacks in prior arts.
SUMMARY OF THE INVENTION
The present invention therefore pertains to a method for preparing a compound having general formula (I) by reacting a compound having general formula (II) with an alcohol having general formula (III) in the presence of hydrogen and a metal catalyst:
wherein:
- R is an alkyl, alkenyl or alkynyl,
- n is an integer between 0 and 20,
- m is an integer between 1 and 3,
- p is an integer between 0 and 2, and
- p+m=3.
The method of the invention enables to alkylate amines by using an environmentally friendly alkylation agent.
Advantageously, it is not necessary to control the flow rate of alkylation agent by using the method according to the present invention.
The invention also concerns a mixture comprising:
(i) A compound having general formula (II) ,
(ii) An alcohol having general formula (III) ,
(iii) Hydrogen, and
(iv) A metal catalyst.

Metals of group IA (Li, Na, K, Rb, Cs, Fr) are also known as alkali metals and metals of group IIA (Be, Mg, Ca, Sr Ba and Ra) are generally referred to as alkaline earth metals.
The metals of group IB, IIB, IIIB, IVB, VB, VIB, VIIB and VIIIB are often referred to as transition metals. This group comprises the elements with atomic number 21 to 30 (Sc to Zn) , 39 to 48 (Y to Cd) , 72 to 80 (Hf to Hg) and 104 to 112 (Hf to Cn) .

Some of the elements encompassed by the description above and understood to be metals for the purpose of the present invention, are sometimes also referred to as metalloids. The term metalloid is generally designating an element which has properties between those of metals and non-metals. Typically, metalloids have a metallic appearance but are relatively brittle and have a moderate electrical conductivity.

After 10 minutes of gas flow, heat the oven with a program at a 1℃/min speed from room temperature to 200℃, and keep at 200℃ 0.5-4 hours depending on the amount ofcatalyst.
After the reduction, stop heating and let the temperature reduced to room temperature. Purge the reduced catalyst with pure nitrogen or argon for 10 minutes at room temperature, and plug the both outlets of the tube with rubber stopper immediately.
The tube is weighed with and without catalyst to get the real weight ofthe catalyst.
The catalyst is used freshly after reduction, or kept in a glove box filled with argon.

The reactor was cooled down to ambient temperature and the hydrogen gas was evacuated carefully in fume hood. To the reaction mixture was added internal standard bisphenyl with accurate weight. After complete dissolving of bisphenyl, the liquid was firstly weighed and then filtered and analyzed by GC. The conversion and yields were calculated using internal standard calibration.
Table 7 Influence of the amount of catalyst on the reaction
Example 7:
Pre-reduced copper containing catalyst Pricat 60/8P was weighed (0.13 g) . A clean autoclave was charged under nitrogen after vacuum&nitrogen exchanges for 3 times, catalyst was transferred into autoclave immediately.
Methanol (1.2 mol, 48mL) and then DETA with a certain quantity described in Table 8 were charged into autoclave under nitrogen subsequently.
The autoclave was well sealed under nitrogen, and purged by hydrogen 10 bar and evacuated for 10 times, finally purged with 40 bar of hydrogen. The sealing of the reactor is checked by waiting 1 hour at room temperature without stirring, and if the pressure remains unchanged then the reactor is well-sealed. Then the reactor was stirred with mechanical stirring for 1 hour at ambient temperature to allow the absorption of the hydrogen, followed by heating up to 200℃ for 20 hours with 500 rounds/min stirring speed. The reactor was cooled down to ambient temperature and the hydrogen gas was evacuated carefully in fume hood. To the reaction mixture was added internal standard bisphenyl with accurate weight.

Table 8 Influence of the concentration of DETA on the reaction
Example 8:
Pre-reduced copper containing catalyst Pricat 60/8P was weighed (0.12 g) . A clean autoclave was charged under nitrogen after vacuum&nitrogen exchanges for 3 times, catalyst was transferred into autoclave immediately.
Methanol (1.2 mol, 48mL) and then DETA (2.7 mmol, 0.28 g) were charged into autoclave under nitrogen subsequently.
The autoclave was well sealed under nitrogen, and purged by hydrogen 10 bar and evacuated for 10 times, finally purged with 50 bar of hydrogen. The sealing of the reactor is checked by waiting 1 hour at room temperature without stirring, and ifthe pressure remains unchanged then the reactor is well-sealed. Then the reactor was stirred with mechanical stirring for 1 hour at ambient temperature to allow the absorption of the hydrogen, followed by heating up to 200℃ for 10 hours with 500 rounds/min stirring speed. The reactor was cooled down to ambient temperature and the hydrogen gas was evacuated carefully in fume hood. To the reaction mixture was added internal standard bisphenyl with accurate weight. After complete dissolving of bisphenyl, the liquid was firstly weighed and then filtered and analyzed by GC. The conversion and yields were calculated using internal standard calibration. The yield of PMDTA was 68.1%.
