Dioctyl sebacate
Dioctyl sebacate (also di (2-ethylhexyl) sebacate, commonly abbreviated as DOS, DEHS, and BEHS) is an organic compound which is the diester of sebacic acid and 2-ethylhexanol . It is an oily colorless liquid and is used as a plasticizer, including in the explosive C4. [3]
Dioctyl Sebacate (DOS) - Chemical Supplier Distributor Chemceed
Application. Dioctyl Sebacate (DOS) is used as a plasticizer for PVC, nitrocelluloses, styrene resins, and synthetic rubbers where low temperature performance is required. DOS is also compliant with FDA CFR 21 for food contact materials. Dioctyl Sebacate can also be used in lubricants to allow more mobility at lower temperatures.
LABORATORY AND FIELD EVALUATION OF CRYSTALLIZED DOW 704 OIL
In 45 collocated PM2.5 tests conducted at three U.S. cities, regression of liquid DOS versus liquid DOW 704 produced slopes, intercepts, and R2 values of 0.995, -0.006 ug/m3, and 0.999, respectively. As a result of these tests, DOS oil has been approved by EPA as a substitute for the ' DOW 704 oil.

- Why is Dioctyl sebacate a good lubricant?
- Dioctyl sebacate is an ester of particular interest due to its high oxidative and thermal stability, excellent lubricity, good biodegradability and moderate production costs and can be used as a synthetic lubricant , , . Dioctyl sebacate can be synthetized by esterification of sebacic acid and octanol, using acid or enzyme catalyst.
- What is Dioctyl sebacate?
- Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?
- ) Dioctyl sebacate (also di (2-ethylhexyl) sebacate, commonly abbreviated as DOS, DEHS, and BEHS) is an organic compound which is the diester of sebacic acid and 2-ethylhexanol.
- Is Dioctyl sebacate synthesis environmentally friendly?
- However, the homogeneous acid catalyzed esterification presents difficulties in product purification, catalyst recovery, and wastewater treatment. On the other hand, dioctyl sebacate synthesis using lipase as catalyst is an environmentally friendly process.
- What is Dioctyl sebacate synthesis using Novozym 435?
- Dioctyl sebacate synthesis via esterification of sebacic acid with octanol can be made using commercial immobilized lipase Novozym 435, leading to high sebacic acid conversion and high dioctyl sebacate yield.
- What is the conversion rate of Dioctyl sebacate?
- Sebacic acid conversion values were close to 100% for all techniques. In the same way, values of diester molar percentage were similar after 150 min. However, initial production rates of dioctyl sebacate were slower in comparison with the reaction in a closed batch reactor (Fig. 4).
- Does enzyme reuse affect Dioctyl sebacate synthesis (relative sebacic acid conversion)?
- Effect of enzyme reuse on dioctyl sebacate synthesis (relative sebacic acid conversion). Each reaction was conducted for 150 min, using 7 wt.% of Novozym 435 and sebacic acid/2-octanol molar ratio of 1:5, at 100 °C. The biocatalyst was washed with n-hexane or 2-octanol. Similar sebacic acid conversions were obtained with the two solvents.
