For the adipates containing short chain, such as dipropyl adipate, dibutyl adipate, diamyl adipate, the phase stability to methanol-gasoline is ineffective, even over 11.1% dosage was used methanol and gasoline cannot homogenize in M15, M30, M50 and M65 at 40oC.
When the chain length of alkoxy group of the adipates increases, diethyl adipate, dimethyl adipate and dipropyl adipate can depress the saturation vapor pressure lower than that of gasoline, among which dipropyl adipate is the most effective one.
The amount of main sulfur constituents (diallyl trisulfide, dimethyl trisulfide, dipropyl
trisulfide, diallyl disulfide, and methyl allyl) was significantly lower in A.

A novel slow-release nitrogen fertilizer poly(carbonyl urea)oligomer (PCUO) was prepared by the condensation polymerization of urea and dipropyl
carbonate (DPrC) at normal pressure, in which anhydrous potassium carbonate was as a catalyst.
The prepacked commercial columns (500 mg) used for prepurification of urine samples before RIA had sorbent beds consisting of native silica unfunctionalized (Si) or silica coated with the following functional groups: ethyl (C.sub.2] octyl ([C.sub.8]), octadecyl ([C.sub.18]), phenyl (PH), aminopropyl ([NH.sub.2]), or dipropyl
ether-1,2-diol covalently linked via the 3' carbon [i.e., -([CH.sub.2])3]O-[CH.sub.2]CH(OH)-[CH.sub.2]OH, abbreviated to "diol"].
They include dipropyl
kentone and hydroxyphenyl-2-butanone.
GC/MS analysis of the authentic S-2 revealed numerous contaminants, including lower chlorinated dipropyl
Based on fertility studies in mice, DEHP is the most potent reproductive toxicant among the phthalates, followed by dihexyl phthalate (DHP), dipentyl phthalate (DPP), DBP, and dipropyl
phthalate (DPrP) (Heindel et al.
A soil-incorporated application of EPTC (S-ethyl dipropyl
carbamothioate) herbicide at 4.3 kg [ha.sup.-1] was made before planting, with the entire area tilled for seed bed preparation.
