Abstract

2-hydroxypropylammonium sulfate of the following formula: [HOCH2CH (CH3) NH3] 2SO4.

Description

A useful model belongs to the 2-hydroxypropylammonium sulfate compound (НОСНеСН(СН3)МНзгз|»5О or |МиИРАНИ5О»Х) not previously described in the literature, which can be used as a multifunctional sulfur- and nitrogen-containing compound - a starting reagent in the synthesis of organic compounds, physiologically active substance, etc.

It is known (Khoma R.E., Znnan A.A., Helmboldt V.O., Shishkin O.V., Baumer V.N. Synthesis, crystal structure, vibrational spectrum and thermochemical transformations of tris(oxymethyl)aminomethane sulfate. Journal. non-organic chemistry. 2014. Vol. 59, Mo. 1. - pp. 60-65. ОО: 10.1134/50036023614010069| that when sulfur oxide (SO) interacts with an aqueous solution of the amino alcohol tris(oxymethyl)aminomethane, the corresponding ammonium sulfate is formed.

Based on the structure and method of production, the above-mentioned ammonium sulfate is the closest analogue of the claimed compound.

The choice of the analogue is due to the fact that it and the claimed compound have common features: the presence of a sulfate anion and the corresponding hydroxyalkylammonium cations in the composition.

The useful model is aimed at expanding the list of hydroxyalkylammonium sulfates.

The task is solved by synthesizing 2-hydroxypropylammonium sulfate.

What is new in the useful model is that, unlike the closest analogue, the received sulfate contains a 2-hydroxypropylammonium cation.

The cause-and-effect relationship between the set of essential features and the achieved technical result is as follows: during the interaction in the system "sulfur oxide ((IM)-2-hydroxypropylamine (MiRA)-water-oxygen)" 2-hydroxypropylammonium sulfate is formed.

The method of obtaining hydroxyalkylammonium sulfate is implemented by bubbling 502 through an aqueous solution of MiRA at 20 "С, followed by isothermal evaporation at room temperature in air until the water is completely removed.

The analysis of nitrogen, carbon and hydrogen content was carried out using an elemental SNM analyzer. IR spectra were recorded on the device 5resigit ВХ II ET-IV bouviet (RegkKkip-EIteg) in the range of 4000-350 cm", samples were prepared in the form of tablets from KVg. Raman spectra were recorded on a laser spectrometer OHC Katap Misgozsore "Tepto Zsiepiis" (wavelength (radiation 532 nm).Ei mass spectra were recorded on the MH-1321 instrument, direct introduction of the sample into the source, energy of ionizing electrons 70 eV.

X-ray diffraction was performed on an automated powder diffractometer 5ietep5z 0500 (geometry

Bragg-Brentano, SiKa radiation, Mi filter). The analysis of the powder X-ray pattern was carried out according to the Rietveld method (EshiRgoi |Koagidoe7-Sagma|za! 9., Koizpe! T., EshiRgoi.98 apa program

The preparation of the |MiIRANI5O4 salt by the proposed method is illustrated by the following examples.

Example 1

2-Hydroxypropylammonium sulfate (I). The solution was poured into a thermostated cell (20 units).

MIRA (0.02 mol) in 30 ml of water and in bubbling mode was passed through it for 50 minutes at a rate of 50 ml-min for 45 minutes (1-20 °C). The resulting solution was kept at room temperature in air until the water was completely removed The isolated white crystalline product I (2.45 g, yield 98.67 95) was not subjected to additional purification.

The individuality of the obtained product was confirmed by various physical and chemical methods.
