Specification

Description

Diisobutyl ketone is used as a solvent fornitrocellulose, lacquers, and synthetic resins;in organic syntheses.;Uses Diisobutyl ketone (DIBK) is a transparent liquid with a distinct odor and a high boiling point. It is an heavy-end byproduct of producing MIBK. DIBK is used in many applications such as nitrocellulose lacquers, synthetic resins, coatings and stains, paint strippers, leather finishings, adhesives, printing and coating inks, cleaning and dregreasing, Flavors and fragrances, solvent and re-crystallization aid for pharmaceuticals, mining, and as a chemical intermediate. DIBK has good activity for many synthetic resins including nitrocellulose, rosin esters, phenolics, hydrocarbons, alkyds, polyesters, and acrylics. It is useful as a retarder solvent to improve flow and minimize humidity blushing. The low density and low surface tension of DIBK enables formulators to develop high-solids coatings with low VOC content and excellent flow and leveling properties. DIBK has excellent viscosity reduction for and reduces surface tension in high solid’s coatings. It has good volume-to-weight advantage over other classes of solvents used in coatings.

Electrochemical Study of 2,6-Dimethyl-4-Heptanone Used to Construct Microliquid/Liquid Interface

Zhang X, et al. Journal of Electroanalytical Chemistry, 2016, 781, 76-82.

Using 2,6-Dimethyl-4-heptanone as the organic phase, the water/ketone interface can be successfully constructed. Thermodynamic data for TPAs+, TBA+, BF4-, IO4- and ClO4- were studied within the available potential window of the water/2,6-dimethyl-4-heptanone interface. The results indicate that 2,6-dimethyl-4-heptanone is suitable for further charge transfer studies (e.g., promoting ion transfer and electron transfer).
Ion transfers at the water/2,6-dimethyl-4-heptanone interface
· 2,6-dimethyl-4-heptanone has a much wider potential window than most of the nonanones. It is likely caused by the existence of the branch structure and its relatively lower permittivity.
· There are no transfers of TMA+, TEA+, TPrA+, TPB-, Br-, and I- which could be observed within the potential window of this system.
· The transfer half-wave potentials are -0.163 V for TPAs+, -0.095 V for TBA+, -0.159 V for BF4-, -0.099 V for ClO4- and -0.075 V for IO4-, respectively.
· TPAs+ and BF4- are relatively difficult to transfer across the water/2,6-dimethyl-4-heptanone interface.

2,6-Dimethyl-4-Heptanone as An Effective Diluent in Glutaric Acid Extraction System

Pehli vanoğlu N, et al. Journal of Chemical & Engineering Data, 2010, 55(9), 2970-2973.

By measuring the reaction extraction equilibrium of glutaric acid aqueous solution and trioctylmethyl ammonium chloride (Aliquat 336) under different diluent conditions, it was found that 2,6-dimethyl-4-heptanone is glutaric acid + Aliquat 336 The most effective diluent in extraction systems, with a distribution coefficient (KD) value of up to 8.51.
Effect of 2,6-dimethyl-4-heptanone as diluent
· The distribution coefficients (KD) values for the diluents used with Aliquat 336 at a 1.31 mol ·L-1 concentration follow the trend: 2,6-dimethyl-4-heptanone (8.51) > 3-methyl-butan-1-ol (7.74) > kerosene (6.37) > decan-1-ol (5.81) > nonan-1-ol (4.97) > octan-1-ol (3.79) > toluene (3.39) > hexan-2-one (2.93) > methyl ethyl ketone (2.47) > hexane (2.29).
· The maximum removal of glutaric acid is 89.92 % with 2,6-dimethyl-4-heptanone at a 1.31 mol·L-1 initial concentration of Aliquat 336. The acid concentration of the organic phase at equilibrium CGA increased from (0.45 to 0.75) mol·L-1 with an increasing amount of Aliquat 336 from (0.22 to 1.31) mol ·L-1 with diisobutyl ketone.
