Synthesis, Characterization, and Evaluation of 10-Undecenoic Acid-Based Epithio Derivatives as Multifunctional Additives
摘要:
Novel epithio compounds from alkyl epoxy undecanoates (n-alkyl, C-1, C-4, and C-6; isoalkyl, C-3, C-4, and C-8) were synthesized using an ammonium thiocyanate in ionic liquid 1-methylimidazolium tetrafluoroborate/H2O (2:1) solvent system in 8590% yields by gas chromatographic (GC) analysis. The synthesized products were characterized by H-1 and C-13 nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy (FTIR), gas chromatography, and GC mass spectral (GC-MS) analyses and evaluated for their antioxidant, extreme pressure (EP), and antiwear (AW) properties in three different base oils, namely, epoxy jatropha fatty acid n-butyl esters (EJB), di-2-ethylhexyl sebacate (DOS), and mineral oil (S-105). Among the synthesized products, n-butyl epithio undecanoate exhibited superior antioxidant property (229.2 degrees C) compared to butylated hydroxytoluene (BHT, 193.8 degrees C) in base oil DOS and comparable performance in EJB and S-105 base oils. All of the epithio derivatives exhibited significantly enhanced weld point for the base oils EJB and DOS at 2 wt % level and displayed moderate enhancement in S-105 base oil. Methyl epithio undecanoate at 0.6% concentration exhibited considerable improvement in the wear scar of DOS base oil. The synthesized epithio derivatives have potential as multifunctional additives in lubricant formulations.
An electrostatic inkjet ink composition comprising: a non-aqueous solvent having a dielectric constant of from 1.5 to 20 and a surface tension at 25° C. of from 15 to 60 mN/m; a color material that is insoluble in the non-aqueous solvent; and a charge control agent that is soluble in the non-aqueous solvent, wherein the charge control agent contains a half-aside maleic acid copolymer containing repeating units represented by the formulae (Ia) and (Ib) as defined herein.
A W/O/W emulsion composition having high emulsion stability, which can be prepared extremely easily and for which the production efficiency of the W/O/W emulsion product is favorable, and a method of producing such a W/O/W emulsion composition. The W/O/W emulsion composition of the present invention includes 0.001 to 60% by mass of a component (A) described below and 0.001 to 10% by mass of a component (B) described below; wherein, a mass ratio between the component (A) and the component (B) is within a range from 1:0.01 to 1:1.4. Component (A): a sugar fatty acid ester composition obtained by esterifying a sugar and a fatty acid of 8 to 28 carbon atoms, in which a hydroxyl value of said sugar fatty acid ester composition is within a range from 20 to 220. Component (B): a nonionic surfactant having an HLB value of not less than 7.
The present invention relates to a process for producing a stretched molding which comprises stretching a straight chain random copolymer having:
a repeating unit (A) represented by the formula:
CH₂-CH₂
and a repeating unit (B) represented by the formula:
the proportion of said repeating unit (B) being 0.01 to 10 mol%; and
an intrinsic viscosity [η] as measured at 135°C in decalin of at least 5 dℓ/g.
A stretched molding obtained by the present invention has mechanical properties equivalent or superior to those of the conventional super high molecular weight polyethylene stretched molding and is excellent in adhesive properties, dyeability, printability and so on, and thus is greatly useful as an industrial material required to have high strength and further good adhesive properties and printability.
