It is known to prepare cyclic phosphinic acid esters in dif-ferent ways. Suitable processes for example are described in US Patent Specifications Nos. 2,916,510, 2,953,591 and 2,648, 695. Little is known up to now about the reactivity of such com-pounds also named phostones or 2-oxo-2-alkyl-1.2-oxaphosphola-nes. US Patent Specifications Nos. 2,916,510 and 2,953,591 on-ly note that the cyclic phosphinic acid esters are chemically stable in a wide temperature range.
It has been manifested surprisingly that these compounds may be reacted in simple manner with primary or secondary, mo-novalent or bivalent, aliphatic or aromatic amines to yield zwitterionic salts of novel phosphinic acids presenting a se-ries of technically rather valuable properties.
The present invention consequently provides zw~itterionic compounds of the formulae O-P-CH-CH-CH - ~ R

or aromatic amines.
R, Rl, R2 and R3 signify hydrogen or simple aliphatic hy-drocarbon radicals such as methyl, ethyl and propyl.
R4 may signify an alkyl, a cycloalkyl or an aralkyl radi-cal such as methyl, cyclohexyl or aralkyl having up to 15 car-bon atoms or an olefinic radical having up to 12 carbon atoms such as an allyl radical.
R5 stands for a bivalent alkylene or aralkylene radical or a cycloalkylene radical such as for example -CH2-CH2-CH2 ~ H2C ~ CH2 ' H ~ 2 ~ H
having up to 25 carbon atoms.
The following equation illustrates the invention:

It may be operated thereby with or without a solvent or a dispersing agent. Highly boiling ethers such as diglycol dimethyl ethers, 25 aromatic compounds such as xylene, chlorobenzene etc. may be used, for example. It is also possible to use one of the star-ting components, for example, the amine, in a greater excess, simultaneously acting as a solvent.

quently are obtained in a quar~titative yield, generally in a cry-stallized form. When heating in the solvent the reaction product generally is obtained in the form of a colorless, crystalline precipitate which may increase by cooling after termination of the reaction and be easily isolated by simple filtration.
The smooth method of carrying out the reaction yielding co-lorless products of a high purity in the case of a number of mono- and diamines with a practically quantitative yield is surprising and unexpected.
As suitable phosphlanes for the reaction there may be men-tioned, for example, 2-oxo-methyl-1.2-oxaphospholane, 2-oxo-2-ethyl-1.2-oxaphospholane, 2-oxo-3-methyl-1.2-oxaphospholane,2-oxo-2-ethyl-4-methyl-1.2-oxaphospholane,2-oxo-2-hexyl-1.2-oxa-phospholane.
Suitable amino compounds, for example, are methylamine, di-methylamine, allylamine, octylamine, cyclohexylamine, methyl-isobutylamine, benzylamine, ethylene amine, diamino propane-1.3, bis-aminomethylcyclohexane, dimethyl-bis-(4-amino-cyclohexyl)-methane.
The novel compounds may be used as anti-static agents, pri-mers for metallic surf~ces, as long-acting desinfectant owing to their absolute resistance to hydrolysis and as flotation and emulsifying auxiliaries. They may moreover be used as interme-diates for the textile finishing and colouring.
The following examples illustrate the invention:

12 g of 2-oxo-2-methyl-1.2-oxaphospholane (0.1 mole) were carefully melt with 9.9 g of cyclohexylamine (0.1 mole) in a Schlenk tube under a nitrogen atmosphere and kept in a heating furnace for 2 days at a temperature of 80 to 90C. The fluid molten mass got viscous after some hours and colorless cry-stalls slowly precipitated therefrom. The mixture solidified within a period of some hours or days to give the analytically pure adduct. Crystallisation may be accelerated in the presen-ce of ethanol or isopropanol. A recrystallisation of the pro-ducts was not required generally.

12 g of 2-oxo-2-methyl-1.2-oxaphospholane (0.1 mole) were carefully melt with 9.9 g of cyclohexylamine (0.1 mole) in a Schlenk tube under a nitrogen atmosphere and kept in a heating furnace for 2 days at a temperature of 80 to 90C. The fluid molten mass got viscous after some hours and colorless cry-stalls slowly precipitated therefrom. The mixture solidified within a period of some hours or days to give the analytically pure adduct. Crystallisation may be accelerated in the presen-ce of ethanol or isopropanol. A recrystallisation of the pro-ducts was not required generally.
