This work explores the relationship between polar and non-polar liquids and their interaction with typical porous coating structures, consisting of 100% dispersed calcium carbonate. The effects of addnl. agents, i.e. isopropanol and ionic/non-ionic surfactant are investigated. These agents are currently being employed and developed for the printing industry. Absorption rates into compressed tablets of ground calcium carbonate, with and without the presence of latex, are observed Polyacrylate dispersant, used in manufacture, renders the pigment surface both hydrophilic and hygroscopic, and therefore controls the differential dynamic wetting characteristics of the porous structure for either polar or non-polar liquids In competition with non-polar hexadecane saturating the pore structure of a latex-free sample, polar water displaces the non-polar liquid instantaneously, causing disintegration of the packed porous structure. In the presence of latex binder, however, the structurally destructive pressure is contained, and the uptake of polar water is retarded. The required pre-wetting action of water vapor diffusion on the carbonate polyacrylate dispersant pigment surface is considered to be an integral part of the successful competition between oil and water in the offset printing process, as non-polar oil absorbs steadily into a water pre-saturated structure. Addnl., isopropanol likely promotes miscibility and emulsification more so than ionic/non-ionic surfactant. This behavior possibly relates to the comparative mol. weights of the agents which differentiate their surface energy modifying mechanism from those of the ionic pigment dispersant and binder stabilizers/carboxylation. The use of addnl. agents enables potentially a more homogeneous response to the competitive imbibition environment within the coating structure. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Name: 2-(2-(Hexyloxy)ethoxy)ethanol).
2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Name: 2-(2-(Hexyloxy)ethoxy)ethanol
