ANION-EXCHANGE EXTRACTION OF ZINC THIOCYANATE COMPLEXES BY NON-SYMMETRIC QUATERNARY AMMONIUM SALTS... 

In this work, the results of study of zinc thiocyanate complexes anion-exchange extraction by non-symmetric QASes in toluene ai e discussed. The non-symmetric QASes have the common formula [(C,3H g03)N(CH3) (C,H Q3 J-X-, where C,3H3 03 - highly lipophilic substituent, (2, 3, 4-tn. s-dodecyloxy)benzyl. It was found that exchange... 

The most stable structures and formation energies of zinc thiocyanate complexes have been calculated by ab initio density functional methods. The formation energies of the linkage isomers [Zn(NCS)4]2. [Zn(NCS)2(SCN)2]2, and [Zn(SCK)4]2 were determined. A comparison of the formation energies indicated that [Zn(SCN)4]2 is the most stable isomer both in water and in dimethyl sulfoxide.567... 

Assume that the reaction between the neutral complex and the solvating molecule takes place at the interface (to assume the reaction to take place in the organic phase would be umealistic, as the zinc thiocyanate is insoluble in hexane) thus the etxraction reaction is... 

Zinc thiocyanate is an analytical reagent. Other applications are dyeing of textiles and as a swelling agent for cellulose esters. 

Complexes with pyridine JV-oxide of zinc thiocyanate and selenocyanate of the stoichiometry ZnLsX2 (X = SCN, SeCN) have been reported.1066 IR evidence shows that they are best formulated as [ZnL6]2+[ZnX4f. ... 

In the presence of suitable catalysts, /3-lactones are formed by the action of ketene on aldehydes and ketones. Many catalysts have been used those preferred for aldehydes include boric acid, triacetyl borate, zinc thiocyanate, and zinc chloride. Ketones require stronger catalysts such as boron ttifluoride etherate. The reactions ate conducted at low temperatures (0-10°) to minimize polymerization of the product. Yields of /6-lactones from formaldehyde and acetaldehyde are 85%. The /3-lactones formed from conjugated olefinic ketones decompose to dienoic acids which isomerize to olefinic S-lactones. ... 

Pyrazolin-5-ones form complexes with both inorganic and organic compounds much more readily than do the 2-pyrazolin-5-ones. The most extensive series of complexes is that formed with a variety of metallic salts. Antipyrine (2,3-dimethyl-l-phenyl-3-pyrazolin-5-one) forms a series of complexes with salts of divalent, trivalent and tetra-valent metals. Two molecules of antipyrine form a complex with one molecule of copper, cadmium, cobalt and zinc salts.266,866,1116 Complexes prepared from metallic nitrates are usually hydrated.1322 There also exists a series of complexes in which three molecules of antipyrine form a complex with one or two molecules of metallic salts. Such complexes form with two molecules of simple ferric salts272 or with one of complex iron cyanides.608 Nitrates of thorium, lanthanum, cerium and samarium also give such complexes.841 This ratio also occurs in some antipyrine complexes with cadmium and zinc thiocyanate.266 A number of salts of rare earths and iron which have complex anions such as thiosulfate, thiocyanate, dithionic acid and complex iron cyanides form complexes in which six molecules of antipyrine are present.405,408 608,841,950 Stannic chloride forms salts containing three or four molecules of antipyrine and hydrochloric acid.46... 

The anionic zinc-thiocyanate complex forms ion-pairs with basic dyes, extractable by e.g., benzene or CCI4 [68]. Use has been made of Rhodamine B [69], Victoria Blue B [70], or Malachite Green [89], with e values within (5-12)-10 [71]. 

Antimicrobials with a metallic ion. This class includes water-soluble salts of zinc, copper, or tin. Zinc salts, in particular zinc citrate, are the most widely used in toothpastes. Other sources of zinc ion are zinc chloride, zinc sulfate, and zinc thiocyanate.
