    Abstract: A water-immiscible organic fluid is tagged and identified by tagging the organic fluid with between about 0.25 and about 100 ppm of a marker compound having the formula: ##STR1## where the OH groups are either ortho or para to the diazo moieties, and the Xs are the same or different and are selected from C.sub.1 -C.sub.12 -alkyl, Cl, Br, F, NH.sub.2, CN, NO.sub.2, NH(C.sub.1-3 -alkyl) and N(C.sub.1-3 -alkyl).sub.2, and the fluid is identified by extracting the tagged fluid with an alkaline aqueous extractant having a pH above about 12 and containing, based on 100 parts by weight of said extractant, between about 10 and about 60 parts by weight of an organic cosolvent having the formula:R.sup.1 --O--R.sup.2 --NH.sub.2 (II)where R.sup.1 is C.sub.1 -C.sub.3 -alkyl, and R.sup.2 is C.sub.2 -C.sub.6 -alkylene.

    Abstract: Multiple amide polyether alcohol compounds of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each independently selected from the group consisting of hydrocarbyl of 2 to 100 carbon atoms and substituted hydrocarbyl of 2 to 100 carbon atoms; R.sub.3 and R.sub.4 are each independently selected from the group consisting of hydrocarbyl of 1 to 100 carbon atoms, substituted hydrocarbyl of 1 to 100 carbon atoms and polyoxyalkylene alcohol of 2 to 200 carbon atoms; R.sub.5 is selected from the group consisting of alkylene of 2 to 20 carbon atoms and alkylene of 2 to 20 carbon atoms having at least one methylene group replaced by at least one oxygen atom or at least one acylated nitrogen atom; x and y are each from 1 to 50 and the weight average molecular weight of the additive compound is greater than about 600 when used as gasoline additives are found to decrease intake valve deposits.
