DOCUMENT TYPE: Journal CA Section: 80 (Organic Analytical Chemistry) Odor sensors were prepd. by coating dialkyl (C1-C18) cyclohexanedicarboxylate films on gold electrode of quartz crystal microbalance. The sensitivities of dialkyl cyclohexanedicarboxylate films to n-pentyl acetate vapor were increased with the increase of carbon no. of the films from C6 to C10. The sensitivities were decreased sharply for the cyclohexanedicarboxylate films contg. C12, C14, C16, and C18 chains. The cyclohexanedicarboxylate with branched C14 chains exhibied the highest sensitivity toward pentyl acetate. The sensitivities of the films contg. 1:1 mixed dialkyl cyclohexanedicarboxylates were also studied. .

CLASS: IC: D06M013-224; D06M015-53; D06M101-30.Several reagents with their cas registry numbers 94-60-0 and 79085-79-3 are used here. APPLICATION: DD 90-342496 5 Jul 1990. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Section cross-reference(s): 37, 40 The title compn., useful on filaments spun from polyesters, polyamides, etc., contains lubricants (e.g., alkoxylated alcs.) and a liq. heat stabilizer RO2C(X)nCO2R (R = C1-4 linear or tertiary alkyl or isoalkyl; X = CH2, cyclohexane-1,4-diyl; n = 1-34). A spin finish compn. contg. lubricants and MeO2C(CH2)34CO2Me was applied to continuous polyester filaments during a spin-stretch-wind operation in the manuf. of reinforcing cords for a rubber conveyor belt. .
