FIELD: process engineering. ^ SUBSTANCE: invention may be used in chemical industry. Proposed mix contains, at least, one alkanolamine, piperazine and water. Total content of amones in the mix exceeds 65 wt %, water-to-piperazine molar ratio varies from 1.6 to 4.8. Alkanolamine-to-piperazine weight ratio varies from 1:7 to 28:1. To produce absorbent, obtained mix is mixed with water and, if required, with alkanolamine. ^ EFFECT: mix with low solidification temperature. ^ 10 cl, 1 dwg, 4 ex |
