Abstract: Disclosed is an organic amine salt foaming agent, that is, a composite polyurethane foaming agent, comprising: 1) hexafluorobutene; and 2) an alkanolamine salt mixture (MAA), the alkanolamine salt mixture (MAA) contains an organic amine salt compound having the following general formula (I): An?[Bm+]p (I); wherein An? is one or two or three selected from the following anions: (b) carbonate: CO32?; (c) formate: HCOO?; (d) bicarbonate: HO—COO?. A polyurethane foaming method using carbon dioxide and an organic amine in combination is also disclosed, in which carbon dioxide is added to a polyurethane composition for foaming. A method for preparing an alkanolamine carbonate salt with low water content from ammonium carbonate and an epoxide is additionally disclosed, in which a liquid alkanolamine salt mixture is used as a dispersion medium or as a solvent for reaction raw material.

Abstract: An organic amine salt compounds of general formula An?[Bm+]p (I) is disclosed, wherein An? is a CO2-donating anion with a valence of ?n, wherein n=1, 2 or 3; each Bm+ comprises: ammonium ion, hydrazinium ion and/or organic amine B cation; wherein m = 1 ? - ? 10 ; 0 < p ? n m ; and wherein An? is one or more selected from a group consisting of following anions: (a) carbamate orcarbazate; (b) carbonate; (c) formate; (d) bicarbonate; (e) organic monocarbonate; (f) organic poly-carbamate; (g) orthoformate; or (h) organic poly-carbonate. The compound of general formula (I) has at least one of hydroxyalkyl group linked to N atom, i.e., has alkanolamine residue. They can be used as polyurethane foaming agent, and most of them can be used as polystyrene foaming agent or polyvinyl choride foaming agent.
