Abstract:
본 발명에 따라 셀룰로오스 수지에 식물유 유래 비방향족 고리형 다이머산 유도체를 친환경 가소제 또는 유동성 향상제로서 함유하는 생분해성 셀룰로오스 수지 조성물은, 수지 자체의 기계적 물성은 크게 저하됨이 없이 용융 온도 및 유리전이온도가 저하되어 가공성이 향상될 뿐만 아니라, 용융가공 시에 아세트산 등의 분해가 억제되어 제품에서의 악취가 방지되고 현저히 개선된 물성을 가질 수 있다.
Abstract:
The present invention relates to a dimer acid alkylene oxide-based nonionic surfactant derived from vegetable oil and a preparation method thereof, wherein the surfactant is environmentally friendly and improves emulsification by containing hydrophilic groups such as hydroxyl groups and hydrophobic groups such as cyclic hydrocarbon groups by preparing dimer acid alkylene diol ester by making dimer acid thermally polymerized in vegetable oil react with alkylene diol and adding alkylene oxide thereto.
Abstract:
PURPOSE: A manufacturing method of highly pure unsaturated fatty acids is provided to remarkably improve the selectivity of separation, to reduce environmental load by reducing the generation amount of waste water, and to save energy costs. CONSTITUTION: A manufacturing method of a highly pure unsaturated fatty acid comprises a step of obtaining glass fatty acid containing highly unsaturated fatty acid by hydrolyzing animal and plant oil waste resource (S1); a step of conducting an element adding-determination method to the mixture of urea and the glass fatty acid containing highly unsaturated fatty acid (S2); a step of adding a surfactant to a collected liquid phase and stirring the mixture (S3); and a step of cooling the liquid phase and separating a highly pure unsaturated fatty acid (S4).
Abstract:
PURPOSE: A norbornene dialkyl ester compound is provided to have excellent thermal stability while maintaining abrasion resistance, and to not contain heavy metal and toxic material. CONSTITUTION: A norbornene dialkyl ester compound is represented by chemical formula 1 which has a dialkyl dithiocarbamate group. In the chemical formula 1: each of R1 is C1-10 alkyl group; and each of R is C4-20 alkyl group or alkenyl group. A manufacturing method of the norbonene dialkyl ester compound comprises: a step of manufacturing a norbonene dialkyl ester by conduct a reaction of dialkyl maleate and dicyclopentadiene; and a step of conduct a reaction of the norbonene dialkyl ester with carbon disulfide and dialkyl amine.
