A number of phenolic ethers of this series show the expected properties. 5-Amino-3-ethoxy-l,2,4-thiadiazole is considerably more soluble in water than its 3-methoxy homolog (3.24 and 0.76 g/100 ml, respectively).88 Their ultraviolet spectra resemble those of the 3-alkyl (or aryl)-5-amino-l,2,4-thiadiazoles.88 3-Alkoxy(or aryloxy)-l,2,4-thiadiazoles are more sensitive towards acids than are the 3-alkyl(or aryl) analogs.88...

Other anionic surfactants, such as nonyl phenol ethoxy phosphate (commercial term) with an aromatic structure, also absorbs in the UV range at 225 nm. Nonyl phenol ethoxy phosphate has two absorption bands (225 nm, 275 nm). The presence of two aromatic rings in the molecular structure of alkyl diphenyloxide disulphonate (commercial term) leads to a bathochromic shift due to an extended conjugation in molecule. In this case, the absorption band is observed at 237 nm.

This formulation has excellent wetting, detergent, rinsing and foaming properties. It is recommended as a medium duty cleaner for truck bodies, floor scrubs, wax strippers, etc. This product is clear from -5C to 70C. This formula would require approximately 4 times as much sodium xylene sulfonate as the amount of Monateric CEM-36 used to achieve clarity. Other nonionic ethoxy-lates, such as those based on primary alcohol or alkyl phenol may... 

Typical enulsifiers used in emulsion polymerization of VC are anirmic emulsifiers like sodium alkyl sulfonates, sodium diaUcyl sulfosucdnates, fatty acid soaps and sodium ethoxy sulfates. Neutral emulsifiers like alltyl phenol ethoxylates and fatty acid ethoxylates are often added during after polymerization in Oder b> increase latex stability. The emulsifiers are not only chosen for control of the particle formation and latex stability during polymerization, but for a number of other reasons like mechanical stability, reactor wall build-up, plastisol formation, heat and colour stability and water resistance of the final product [1].

Among different nonionic surfactant classes, alkyl-phenol ethoxylates (APEOs) comprise the class meriting special attention with respect to environmental issues. The analysis of underivatized alkylphenolic compounds by GC-MS is restricted to the most volatile degradation products, such as alkylphenols and APEOs with less then 4-ethoxy groups. To overcome the problem of volatility, different offline and online derivatization protocols have been developed. Two complementary MS techniques, one using El and another using the less commonly used positive (P)CI, have been evaluated for the analysis of APEOs, their acidic (APECs) and neutral metabolites (APs), and halogenated derivatives. 

Recently [32] photocatalyzed degradation of alkyl phenols and the nonionic nonylphenol ethoxylate were examined. Here the surfactant and alkyl phenols were susceptible to complete mineralization, as showed by the important demonstration of a carbon balance all the way to carbon dioxide (Fig.3) for polyethoxylated 4-nonylphenols with average numbers of 2, 5, and 12 ethoxy units. 

In our system, the acid chloride as the acylating agent was not applicable due to the basic conditions of the proposed transformation and the internal free nitrogen of the piperidyl moiety. However, the trioxifene acylation was adapted by preparing the phenyl ester of 5. Therefore, the required phenyl 4-[2-(l-piperidinyl)ethoxy]benzoate (9) was prepared by alkylating methyl 4-hydroxybenzoate with 2-(l-piperidinyl)ethyl chloride (6). Hydrolysis of the methyl ester provided the carboxylic acid that was converted to the acid chloride (8) using SOCI2 in a mixture of 1,2-dichloroethane and toluene. Acid chloride 8 was then reacted with sodium phenolate to provide 9 as a stable crystalline solid in 64% overall yield from the carboxylic acid.
