“…Often, aluminophosphates are doped with specific metals, whereby the metal ions replace the aluminium ions within the framework. This process is frequently used in the manufacture of single-site catalysts [230], allowing for its use in particular reactions, such as in the oxidation of hydrocarbons [231] or the esterification of acetic acid [232]. One notable example of the use of the metal aluminophosphate being used in the fine chemical industry features in a research paper on the production of biphenyl urea [233].…”

Fine chemicals are produced in small annual volume batch processes (often <10,000 tonnes per year), with a high associated price (usually >USD 10/kg). As a result of their usage in the production of speciality chemicals, in areas including agrochemicals, fragrances, and pharmaceuticals, the need for them will remain high for the foreseeable future. This review article assesses current methods used to produce fine chemicals with heterogeneous catalysts, including both well-established and newer experimental methods. A wide range of methods, utilising microporous and mesoporous catalysts, has been explored, including their preparation and modification before use in industry. Their potential drawbacks and benefits have been analysed, with their feasibility compared to newer, recently emerging catalysts. The field of heterogeneous catalysis for fine chemical production is a dynamic and ever-changing area of research. This deeper insight into catalytic behaviour and material properties will produce more efficient, selective, and sustainable processes in the fine chemical industry. The findings from this article will provide an excellent foundation for further exploration and a critical review in the field of fine chemical production using micro- and mesoporous heterogeneous catalysts.

“…[9] Over the past few decades, a variety of catalysts have been developed for methylation reactions. Researchers have primarily focused their efforts on investigating catalysts based on PO x and Al 2 O 3 based catalysts, such as AlÀ PÀ O, [10][11][12][13] modified MÀ AlÀ PÀ O (M=Ti, Zr, K), [14][15][16] metal phosphates MÀ PÀ O (M=La, Ce, Mg, Zn), [17] modified γ-Al 2 O 3 , [18,19] sodium aluminosilicate catalyst [20] and sulphate-modified zirconia. [21] These catalysts are designed to achieve region-selective O-methylation of catechol with methanol.…”

P2O5 has been widely used as an acid‐base catalyst for the O‐methylation of catechol to guaiacol due to its suitable acid strength; however, its stability, which is a significant concern for industrial applications, has not seen significant breakthroughs. Herein, we developed a facile impregnation strategy to synthesize Ce promote P2O5 supported on mesoporous silica (CeP/SBA). The CeP/SBA‐500 carbonized at 500 °C exhibited the highest catalytic activity with a catechol conversion of 71.5 %. The high activity stems from the addition of Ce, forming CePO4, which exhibits improved surface acidity compared to P2O5. Importantly, chemisorption and in situ infrared studies revealed that CePO4 shows stronger adsorption of catechol, which then rapidly converts to guaiacol. The CeP/SBA‐500 exhibits excellent stability with no activity decrease after 10 h of continuous flow reaction, attributed to the absence of a decrease in CePO4 surface acidity.
