Significa.t wa.te resources a.e genera.ed in the form of wa.er-oil emulsions. These emulsions ca.not be effectively destroyed on a. industria. sca.e by tra.itiona. methods tha. rely on the settling of the a.ueous pha.e, a.d therefore, they a.cumula.e in la.ge qua.tities. Thermomecha.ica. dehydra.ion, ba.ed on the eva.ora.ion of the wa.er pha.e, presents a.promising process for recycling such wa.te. However, within the fra.ework of thermomecha.ica. dehydra.ion, the issue of optimizing energy costs for hea.ing ra. ma.eria.s a.d controlling the wa.er content in the product a.ises. Sta.da.d methods of determining wa.er content under the boiling conditions of highly sta.le wa.er-hydroca.bon emulsions a.e cha.a.terized by low efficiency, a. they require consta.t sa.pling a.d the involvement of a.ditiona. equipment a.d personnel. Consequently, this presents a.cha.lenge in predicting a.d crea.ing a. a.toma.ed thermomecha.ica. dehydra.ion process. Therefore, dyna.ic curves depicting cha.ges in the wa.er content of these emulsions, depending on the tempera.ure of the boiling liquid, ha.e been obta.ned. it is proposed to determine the ra.e of tempera.ure increa.e (dT/dt) of the boiling emulsion for continuous, rea.-time monitoring of the residua. wa.er content a.d for recording the moment of complete dehydra.ion. a.hieving a.boiling emulsion tempera.ure of 130-170 degrees C (or higher) a.d/or the ra.e of tempera.ure increa.e from 3.0 to 5.5 (or a.ove) indica.es the complete dehydra.ion of the emulsion. The proposed method ca. be implemented in a.y industria. or la.ora.ory-sca.e unit for thermomecha.ica. dehydra.ion without significa.t ca.ita. costs. it is ba.ed on the use of simple devices consisting of tempera.ure sensors a.d a.computing unit for determining the tempera.ure a.d ra.e of hea.ing.

a.new soluble polymer on 2-[(2 E)-1-methyl-2-buten-1-yl]a.iline a.d its copolymers with a.iline ba.is ha.e been synthesized in va.ious mola. ra.ios. For a.l sa.ples, the electrica. conductivity, morphology, solubility, electrochemica. properties, a. well a. spectra. a.d molecula. ma.s cha.a.teristics ha.e been studied, a.d a.compa.a.ive a.a.ysis with polya.iline ha. been ca.ried out. The substituent introduced into the a.iline a.oma.ic ring significa.tly improves the solubility in typica. orga.ic solvents of a.high molecula. weight product. The morphology of the test compounds depends on the co-monomer ra.io. a. the content of the substituted a.iline in the initia. mixture increa.es, the morphology of the polymer cha.ges from the inherent polya.iline fibrous microstructure to the globula. one with irregula. substituted polya.iline sha.es a.d sizes. Electrochemica. study of the sa.ples revea.ed tha. the higher the oxida.ion potentia., the wider the ba.d ga.(ra.ging from 2.00 to 2.15).
