Cellosolve and Its Derivatives in Nitrocellulose Lacquers¹

Densities and Refractive Indices of Glycol Ether-Water Solutions.

“…Earlier Data Authors data (2, 5) Authors (9) (3) the two density curves, the change in density with composition is relatively slight; hence, analysis by density is not satisfactory. However, above 65 and 55 weight % on solutions of ethylene glycol monomethyl ether and ethylene glycol monoethyl ether respectively, density may be used in determining the glycol ether content to within ±0.1 weight % for both compounds.…”

“…were also obtained. Although values of these properties have been reported in the literature (2,3,5,9) for the pure glycol ethers, no data have been given for aqueous solutions.…”

Surface Tension and Density of Ethylene Glycol Monobutyl Ether–Water Mixtures from 277.15 to 308.15 K

“…3−8 EO provides an important surface activity, making EGBE one of the smallest surfactants. EGBE application scope covers several uses: as a component in fracturing and drilling fluids for the petroleum industry, 9,10 as an additive in ink, lacquers, varnishes, and enamels in the painting industry, 11,12 and as a cosurfactant in cleaning products, 13−15 among others. To predict its performance in such applications, it is important to know its physical properties, especially the surface tension behavior in aqueous systems.…”

“…The alcohol from which it is synthesized ( n -butanol) is partially soluble in water at room conditions, with an upper critical solubility temperature ( T = 403.1 K and a molar fraction of 0.1070). , The addition of an ethylene oxide (EO) molecule, as part of the hydrophilic region, dramatically changes its physical properties to a completely miscible solvent in water at room temperature and the phase diagram changes to a closed two-phase loop with an upper and lower critical solubility temperature (around 402.86 and 322.12 K for the upper and lower critical solution temperature, respectively). − EO provides an important surface activity, making EGBE one of the smallest surfactants.

Πειραματική Και Θεωρητική Μελέτη Του Ενδο- Και Δια-Μοριακού Δεσμού Υδρογόνου Σε Αλκοξυαλκοόλες

“…Το εμπορικό όνομα του μονοαιθυλαιθέρα της αιθυλενογλυκόλης είναι κελοσόλβ (cellosolve) και με αυτό το όνομα συναντάται σε παλαιότερες δημοσιεύσεις, ενώ η επίσημη χημική ονομασία κατά IUPAC είναι 2-αιθοξυαιθανόλη. Χρησιμοποιείται στη βιομηχανία αυτοκινήτων και επίπλων ως διαλύτης, ως αφαιρετικό βερνικιών, ως σταθεροποιητής γαλακτωμάτων [Reid, 1928, Merck Index, 1989, καθώς επίσης και ως διαλύτης υλικών βαφής στην υφαντουργία, στην επεξεργασία δέρματος και στην τυπογραφία, ως αραιωτικό υγρών για υδραυλικά φρένα, στον αντικολλητικό σχηματισμό ολοκληρωμένων κυκλωμάτων, στη βιομηχανία ημιαγωγών και ως διαλύτης εντομοκτόνων και φυτοκτόνων [Kirk-Othmer, 1994]. Τέλος, ενώσεις που περιέχουν στην αλυσίδα τους έναν αριθμό αιθερικών ομάδων και, δύο, μία ή καμία πρωτοταγή ομάδα υδροξυλίου, χρησιμοποιούνται συχνά ως πρότυπα βαθμονόμησης στην υγρή χρωματογραφία.…”
