“…Therefore, reliable models have been developed by Maurer and co‐workers to explicitly take into account both intermolecular forces and chemical Reactions (1) and (2) to successfully describe the vapor–liquid equilibria (VLE) of aqueous formaldehyde mixtures (HCHO–H 2 O) . As new and reliable data for the system (HCHO–H 2 O) became available, these models have been continuously updated …”

BACKGROUND: Trioxane (C 3 H 6 O 3 ) is industrially produced from aqueous formaldehyde (HCHO) solutions through catalytic distillation catalyzed by sulfuric acid (H 2 SO 4 ). Optimizing industrial process of the synthesis and developing new catalysts require a reliableCONCLUSIONS: The prediction results uncover that, in addition to its ability to accelerate the reaction, the catalyst H 2 SO 4 has strong abilities to increase the activity of 'real' reactant for trioxane synthesis and to promote the phase separation that is very important for drastically increasing the yield of trioxane, reducing the energy requirement for the trioxane synthesis, and decreasing the formation of the by-product formic acid. EXPERIMENTAL MaterialsThe reagents and components along with their supplier and purity are shown in Table 1. Aqueous solutions of formaldehyde wileyonlinelibrary.com/jctb

“…Performing chemical processes using metal catalysts has been considered due to the less cost of operational design in industrial sizes; due to the fact that they are in more suitable conditions in terms of temperature and pressure. Nowadays, a wide range of chemical materials are produced by catalytic conversion process for industrial purposes [9][10][11][12][13][14][15]. Several methods have been proposed for production of formaldehyde by oxidation of hydrocarbon gases, that is to say that, increasing formaldehyde levels is also done by these processes.…”

Formaldehyde is considered as the natural organic material with the equation of CH2O (H-CHO) and the simplest form of aldehydes; in respect of the way, Formaldehyde is one the major significant precursors to numerous types of chemical components. The objectives of this comprehensive study is the methanol oxidation and its conversion to formaldehyde have been experimentally investigated. To do this water and methanol are used as two strategic components in chemical industries and, the feed stream is used to produce formaldehyde in a pilot reactor. Subsequently, due to the presence of water and oxygen in the process of methanol oxidation, the conversion factor has a dramatic increase from 50 percent to approximately 75 in the length of catalytic bed.
