Investigation is carried out to improve production technology of organic alginate aerogels. It is proposed within the investigation to carry out the solvent exchange stage, an important stage of organic aerogels production, under pressure in a carbon dioxide medium in the same apparatus used for supercritical drying. The phase behavior in the system \u201ccarbon dioxide\u2013water\u20132-propanol\u201d, which arises during such a solvent exchange stage, is studied theoretically. An experimental study of the process of step-by-step solvent exchange under pressure was carried out through multiphase and homogeneous regions of the phase diagram of such a system. As a result, new highly efficient technology for the production of organic aerogels was proposed, which can be implemented by combining the two main stages of the process.<\/jats:p>","DOI":"10.3390\/gels7010004","type":"journal-article","created":{"date-parts":[[2021,1,5]],"date-time":"2021-01-05T11:51:39Z","timestamp":1609847499000},"page":"4","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Investigation of Aerogel Production Processes: Solvent Exchange under High Pressure Combined with Supercritical Drying in One Apparatus"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6765-7563","authenticated-orcid":false,"given":"Artem","family":"Lebedev","sequence":"first","affiliation":[{"name":"International Center for Transfer of Pharmaceutical and Biotechnology, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ekaterina","family":"Suslova","sequence":"additional","affiliation":[{"name":"International Center for Transfer of Pharmaceutical and Biotechnology, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksander","family":"Troyankin","sequence":"additional","affiliation":[{"name":"International Center for Transfer of Pharmaceutical and Biotechnology, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8709-4139","authenticated-orcid":false,"given":"Daria","family":"Lovskaya","sequence":"additional","affiliation":[{"name":"International Center for Transfer of Pharmaceutical and Biotechnology, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,5]]},"reference":[{"key":"ref_1","unstructured":"McHugh, M., and Krukonis, V.
