Other words that entered Englishat around the same time include: barrage, output, pickup, pipeline, superheat-ic is a suffix forming adjectives from other parts of speech, occurring originally inGreek and Latin loanwords (metallic; poetic; archaic; public) and, on this model, used as an adjective-forming suffix with the particular senses“having some characteristics of” (opposed to the simple attributive use of the basenoun) (balletic; sophomoric); “in the style of” (Byronic; Miltonic); “pertaining to a family of peoples or languages” (Finnic; Semitic; Turkic)Examples of 'phthalic' in a sentencephthalic Diamides were synthesized by the reaction of phthalic acid and amines.The yield of phthalic anhydride strongly depends on the activity and stability of the catalyst.This catalyst was used for the polycondensation of the tetrahydrofuran with phthalicanhydride.In both studies an undetermined isomer of methylphthalic acid was detected in addition to phthalic acid.Compounds 7–9 were synthesized by reacting hydrazide 4 with phthalic anhydride, 1,8-naphthalene anhydride or acetophenone derivatives.The contaminated tea infusion showed brown stain, and produced a group of toxic materials named phthalic acid esters.Results confirm the presence in waters of such substances as phthalic esters, polybrominated diphenylethers, and organic tin compounds.In addition, the electrical conductivity of chitin modified with phthalic anhydride and trimellitic anhydride was also measured.This electrolytic investigation offers an attractive alternative method for the destruction of industrial effluents contaminated with phthalic anhydride.Three alkyd resins of medium oil length were prepared using phthalic anhydride, maleic anhydride, and glycerol at stipulated ratios. |
