В рамках формальной химической кинетики получены уравнения, связывающие концентрации реагентов, объём капель, состав газовой среды и скорость процессов. На их основе создана компьютерная модель и построены кинетические кривые, демонстрирующие размерные эффекты, для ряда реакций второго порядка (соединения, обмена, конденсации, полимеризации, поликонденсации).</p></abstract><trans-abstract xml:lang="en"><p>Size effects in chemical kinetics are of interest for technologies in which chemical synthesis occurs di- rectly in a spray. The equations are obtained in the framework of formal chemical kinetics that relate the con- centrations of reagents, the volume of drops, the initial composition of the solution, the composition of the gas- eous medium, and the rate of processes. The computer model was created on their basis. Kinetic curves are constructed for a number of second-order reactions (compounds, exchanges, condensations, polymerizations, polycondensations) that demonstrate size effects.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>химическая кинетика</kwd><kwd>размерный эффект</kwd><kwd>спрей</kwd><kwd>компьютерное моделирование</kwd><kwd>кинетическая кривая</kwd><kwd>полимеризация.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chemical kinetics</kwd><kwd>size effect</kwd><kwd>spray</kwd><kwd>computer simulation</kwd><kwd>kinetic curve</kwd><kwd>polymerization.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Leng J. et al.
