摘要:
The present disclosure is related to a catalyst for PIR/PUR foam production comprising a compound having the general formula (I) wherein R
1
and R
2
are independently selected from a C
1
-C
18
straight-chain or branched alkyl group, unsubstituted or substituted with one or more hydroxyl, amino or aminoalkyl groups, or R
1
and R
2
, taken together, form a 5- or 6-membered ring or 7-membered bicyclic structure, one of the members of the ring or bicyclic structure being X, wherein X is selected from CH
2
, O, S, NCH
3
or NCH

COOM, wherein R
3
and R
4
are independently selected from hydrogen or a C
1
-C
4
straight-chain or branched alkyl group and wherein M is an alkali metal ion or a quaternary ammonium ion, as well as to a process for production of said compound and uses thereof and to a process for the production of PIR/PUR foam or flexible foam in the presence of the catalyst of the present disclosure.
