  ZSM-5纳米晶上由醇和DMC合成不对称碳酸烷基酯

  摘要：

  已经实现了使用DMC的新型异质酸（纳米晶体ZSM-5）催化醇的羧甲基化为不对称的碳酸烷基酯。通过水热结晶合成了晶体大小为20–30 nm的纳米晶体ZSM-5（NZSM-5）。合成的NZSM-5通过X射线衍射，傅立叶变换红外光谱和固态NMR进行验证。透射电子显微镜和扫描电子显微镜证实了NZSM-5的形态，揭示了由纳米大小（20-30 nm）的NZSM-5颗粒堆积形成的沸石（100-200 nm）聚集体的形成。NZSM-5的理化性质通过氮的吸附和程序升温的氨解吸来测量，这表明表面积为465 m 2 g -1酸度为0.936 mmol g -1。本协议为高产量的各种非对称碳酸烷基酯提供了一种有吸引力的方法。催化剂被有效地循环多达5个连续循环。这种方法拓宽了DMC在绿色化学中可能的利用范围。

• The Continuous Acid-Catalysed Etherification of Aliphatic Alcohols Using Stoichiometric Quantities of Dialkyl Carbonates

  A range of methyl and ethyl ethers of aliphatic alcohols have been synthesized cleanly in high yield by reacting the corresponding alcohol with dimethyl carbonate or diethyl carbonate over the solid acid catalyst, gamma-alumina. The reaction could be conducted at ambient pressure without the need for the large excess of dialkyl carbonate as previously reported in tie literature. If the reaction was conducted at high pressure, the conversion of the starting alcohol was greatly reduced. However, high pressure CO2 can be used as the solvent without significant reduction in yield. This has implications for tandem reactions.

  The present application relates to a cosmetic composition comprising at least one carbonic acid ester corresponding to formula (I) below: R1—O—CO—O—R2   (I) in which R1 and R2 are identical or different and represent a linear or branched hydrocarbon-based radical, with the proviso that: when R1 and R2 are linear, they each contain from 1 to 6 carbon atoms, with 6≦R1+R2≦7; and when R1 and/or R2 are branched, they each contain from 1 to 8 carbon atoms, with 6≦R1+R2≦9. This composition can be used as a product for caring for and/or making up keratin materials, in particular the skin, the lips and/or the integuments.
