In the present study, an anionic surfactant, sodium dodecyl sulfate (SDS), was investigated, focusing on the determination of various properties (surface tension, critical micelle concentration, micelle size, turbidity) in the presence of alcohols and, in particular, the inhibition of the precipitation of SDS with calcium ions. The calcium ions were added to the surfactant in increasing concentrations (3.0\u201310.0 g\/L), and short-carbon-chain alcohols (methanol, ethanol, n-propanol and n-butanol) were used to shift the onset of precipitate formation. The critical micelle concentration (CMC) of SDS in the presence of alcohols was also determined. It was established that among these alcohols, methanol and ethanol did not exert significant effects on the solubility of the Ca(DS)2 precipitate, while n-propanol and n-butanol were found to be much more efficient inhibitors. In addition, all the alcohols in the applied concentration range (up to 20 V\/V%) were found to decrease the critical micelle concentration of SDS.<\/jats:p>","DOI":"10.3390\/ma17081806","type":"journal-article","created":{"date-parts":[[2024,4,15]],"date-time":"2024-04-15T03:56:13Z","timestamp":1713153373000},"page":"1806","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Application of Alcohols to Inhibit the Formation of Ca(II) Dodecyl Sulfate Precipitate in Aqueous Solutions"],"prefix":"10.3390","volume":"17","author":[{"given":"Csaba","family":"B\u00fas","sequence":"first","affiliation":[{"name":"Department of Molecular and Analytical Chemistry, University of Szeged, D\u00f3m Square 7-8, 6720 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7145-6863","authenticated-orcid":false,"given":"Marianna","family":"Kocsis","sequence":"additional","affiliation":[{"name":"Department of Molecular and Analytical Chemistry, University of Szeged, D\u00f3m Square 7-8, 6720 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9280-3406","authenticated-orcid":false,"given":"\u00c1ron","family":"\u00c1goston","sequence":"additional","affiliation":[{"name":"Department of Physical Chemistry and Material Science, University of Szeged, Rerrich B\u00e9la Square 1, 6720 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c1kos","family":"Kukovecz","sequence":"additional","affiliation":[{"name":"Department of Applied and Environmental Chemistry, University of Szeged, Rerrich B\u00e9la Square 1, 6720 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9406-8596","authenticated-orcid":false,"given":"Zolt\u00e1n","family":"K\u00f3nya","sequence":"additional","affiliation":[{"name":"Department of Applied and Environmental Chemistry, University of Szeged, Rerrich B\u00e9la Square 1, 6720 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1407-0950","authenticated-orcid":false,"given":"P\u00e1l","family":"Sipos","sequence":"additional","affiliation":[{"name":"Department of Molecular and Analytical Chemistry, University of Szeged, D\u00f3m Square 7-8, 6720 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1016\/j.petlm.2016.11.007","article-title":"Most common surfactants employed in chemical enhanced oil recovery","volume":"3","author":"Negin","year":"2007","journal-title":"Petroleum"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"154","DOI":"10.1002\/apj.1640","article-title":"Comparison of the effects of wettability alteration and IFT reduction on oil recovery in carbonate reservoirs","volume":"8","author":"Sheng","year":"2013","journal-title":"Asia-Pac.
