Cholesterol ester compound and preparation method and application thereof

The invention discloses a cholesterol ester compound and a preparation method and application thereof and relates to the field of manufacture of lubricant modifiers. The cholesterol ester compound hasthe following molecular structure, wherein n is one of 6, 8, 10, 12, 14 and 16, and m is one of 2, 4, 6, 8 and 10. An intermediate product is generated from cholesterol and a binary acid under activator and catalyst condition; the intermediate product is subjected with secondary esterification with any one of 1-hexanol, 1-octanol, 1-decanol, 1-dodecanol, 1-tetradecanol, and 1-hexadecanol; the cholesterol portion in the cholesterol lipid compound is of angled sheet structure; such structure, polarity of ester groups and hydrotropy of long-chain alkyl synergically allow the cholesterol esters to be possibly applicable to lubricant additives; the cholesterol ester compound may act as a lubricant friction modifier applied in lubricant production.

A new class of star-shaped cholesteric liquid crystal containing a 1,3,5-trihydroxybenzene unit as a core

A new class of star-shaped cholesteric liquid crystals were designed and synthesized, which used 1,3,5-trihydroxybenzene unit as a core and ω-cholesteric alkyl diacid monoester as mesogenic arm. Their chemical structures were confirmed by element analyses, FT-IR, and 1H NMR. The mesomorphic properties and thermal stability were investigated by differential scanning calorimetry, thermogravimetric analysis, polarizing optical microscopy, and X-ray diffraction measurements. The experimental results demonstrated that the mesogenic arm structures strongly affected the phase behavior. 4a did not show any liquid crystallinity, while 4b, 4c and 4d revealed reversible cholesteric phase transition. As the intermedius alkyl chain of the star-shaped compounds lengthened (from n = 2 to n = 8), their melting points decreased but mesomorphic temperature ranges increased. Focal conic texture, one of cholesteric phase can be observed in the liquid crystalline state.
