“…This is a well known problem within the field and different ways of protecting the pigment, usually referred to as inhibition, have been summarized in a review article [3]. Whereas sodium dodecyl phosphate (SDP) and other surfactants of the alkyl phosphate type were found to be efficient inhibitors, sodium dodecyl carboxylate only provided marginal protection and sodium dodecyl sulfate (SDS) and fatty alcohol ethoxylates were completely inefficient as inhibitors [4]. These observations were correlated to the strength of the interaction of the amphiphile with the pigment surface, as determined by quartz crystal microbalance with dissipation monitoring (QCM-D) and other techniques [5,6].…”

“…In fact, it was shown [34] that DDP provided very effective protection of pigments. Like the other phosphates studied (Alk = C 14 H 29 , C 16 H 31 and C 18 H 35 ), the minimum concentration where DDP starts to be effective as a corrosion inhibitor is around or below the critical micelle concentration (CMC).…”

“…In this respect, it is interesting to compare two surfactants, sodium dodecyl sulfаte (SDS) and sodium dodeсyl phosphate (DDP). These studies performed by P. Carlson et al [8,9,[33][34][35] were initiated by the need to prevent corrosion of aluminum microparticles that may be used as pigments in waterborne printing "silver" inks or in protective primers.…”

This article continues the review of studies (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) dealing with the passivation of various metals by solutions of organic corrosion inhibitors. It provides an overview of papers on the passivating properties of organophosphates, their complexes and salts. The results of corrosion and electrochemical studies, as well as studies on the composition and structural features of surface layers on metals by a variety of physicochemical methods are considered. Organic phosphorus compounds are often called organophosphates, especially in the case of pesticides and even toxic agents. Of course, it is unlikely that such materials have application prospects for the inhibition of metal corrosion. That is why in this series of reviews we consider organophosphates in a narrower sense limited to phosphoric acid esters and their salts, as well as phosphonic acids, their salts or complex compounds with metal cations [1][2][3][4]. The easy synthesis of acid esters of phosphoric acid, the stability of mono-and disubstituted ester anions, their ability to form complexes and hydrophobic passive films on oxidized metal surfaces has been known for a long time [1]. They can be used for the passivation of phosphated metal surfaces, and their salts with amines are used within deicing formulations. These salts can inhibit not only corrosion but also formation of deposits, so they are used in two-phase systems in the oil industry. Since higher homologues are more effective, the solubility of alkylphosphonic acids is commonly increased by ethoxylation. Salts of these acids are used in cooling lubricants, e.g., waterbased cutting fluids. The low toxicity, ability to be chemisorbed on a metal surface, and some useful technological properties of acid esters of phosphoric acid continue to motivate researchers to look for effective corrosion inhibitors of various metals among these compounds and to study their protection mechanisms [5][6][7][8][9][10][11][12][13][14]. Key words: metal corrosion, inhibitors, metal passivation, organophosphates.

“…Aluminum pigment has increasingly been used in various kinds of applications over the past few decades [1][2][3]. It acts as tiny mirrors and selectively reflects light close to a special angle, which is known as the flip-flop effect or metallic effect; so it has widely been applied in automotive coatings, industrial coatings, printing inks, and plastic materials.…”

Application of Cross‐Flow Microfiltration for Purifying Solvent Naphtha with Ceramic Membranes

et al. 2011

The microfiltration process of solvent naphtha 200 containing impurities was studied using multichannel ceramic membranes with pore diameters of 0.5 and 0.8 lm. The effects of operating time, transmembrane pressure, cross-flow velocity, and temperature on permeate flux and rejection were investigated. The scanning electron microscop and energy dispersive spectrometry were conducted for the clean and fouled membranes. Effect of backflushing on permeate flux was also studied. Results show that it is possible to recover over 94 % of the original flux by a program of backflushing. A concentration process was carried out and furthermore, various membrane resistances were calculated. Finally, commercial detergent, HNO 3 , and NaOH + NaClO cleaning stages were used for the 0.5-lm membrane.
