Abstract:
본발명은천연오일로부터타우린계계면활성제를제조하는방법에관한것으로, 상기제조방법은, 추가가공없이타우린과천연오일의직접적인반응을통해타우린계면활성제를제조하고, 공정단계를최소화하였으므로, 종래제조방법을대체하여유용하게사용될수 있고, 대량생산에도적용할수 있다. 또한, 상기제조방법으로제조된타우린계계면활성제는글리세롤이포함되어있어추가첨가제를사용하지않아도되는바, 효율적인원료로사용될수 있고, 물성및 세척력이우수하고, 세정용조성물및 세제로제조하였을때도세척력이우수하며, 특히, 미세먼지세척력이우수한바, 세정용조성물및 미세먼지세정용조성물에적용하여유용하게사용될수 있다.
Abstract:
The present invention relates to a phenylenediamine based antioxidant compound for bio-diesel and a fabrication method of the same. A phenylenediamine based antioxidant is useful as an antioxidant compound for improving the oxidation stability of the bio-diesel by having high activity on antioxidation because the antioxidant supplies hydrogen to a radical and becomes a phenoxy radical which is stabilized by resonance.
Abstract:
PURPOSE: A yellow azo disperse dye is provided to obtain the same concentration of color even from a small amount of dye when dying because of excellent lightproof, inside sublimability, dispersability, and a high molar extinction coefficient, is also environmentally friendly, and reduces the production costs.
