, p. 992 - 993 (2001)
A novel reusable Lewis acid catalyst has been prepared by the heterogenization of a Lewis acid/tetrapropylammonium adduct; anchoring of tin chloride on quaternary ammonium chloride functionalized MCM-41 yielded a catalyst with higher activity compared to the corresponding silica analogue in terms of turnover rates and product yield in the Prins condensation of isobutene and formaldehyde to isoprenol.
Revisiting the Structural Evolution of Hydrotalcite-Derived Mixed Metal Oxides upon Alkali Metal Doping and Its Impact on Base Catalysis

The structural evolution of classic coprecipitation-derived Mg?Al mixed oxide (MMO) upon doping of different alkali metals in a wide level (1–20 wt.%) was revisited. The pristine lateral MMO of aggregates into particulates, accompanied with the dramatic loss of the surface areas and the formation of aluminates. These phenomena become severer with the decrease of the atomic radius. The formation of NaAlO2 likely occurs via the gradual dealumination of the MMO, which is highly dependent on both the dopant content and the activation temperature. This leads to ultimately a new ensemble with MgO as the core decorated by NaAlO2 in the outer surfaces at high Na doping level and above 973 K. When evaluated in the base-catalyzed transesterification and acylation model reactions, the Na-doped MMO show enhanced performance and a plateau at increasing doping that might be explained by an interplay between the number and strength of strong basicity.

Paragraph 0040-0062, (2019/04/17)
The invention discloses a method of using isobutylene and methanol for preparing 3 - methyl - 3 - butene - 1 - ol, its steps mainly are: first nitrogen purging stainless steel high-pressure reaction vessel, replacing the air in the reaction vessel; the methanol liquid added in a reaction vessel, then the isobutylene gas into the reaction container, the high-pressure nitrogen pressurization, make isobutene liquefied, with methanol to form a mixed solution; adding a catalyst in a fixed bed, and then pumped to the isobutene with methanol mixed solution in a fixed bed, into the oxygen-containing gas to react, cooling discharging after completion of the reaction, distillation is 3 - methyl - 3 - butene - 1 - ol. The method of the invention using methanol instead of toxic formaldehyde, environment friendly, the preparation cost is reduced, simplifying the process, and using the fixed bed reactor, can be continuously produced, has high production efficiency and product quality.
