Today there are two main routes: oxidation-dehydrogenation using a silver catalyst involving both the complete or incomplete conversion of methanol; and the direct oxidation of methanol to formaldehyde using metal oxide catalysts (Formox process). In the silver catalyst route, vapourised methanol with air and steam is passed over a thin bed of silver-crystal catalyst at about 650oC. Formaldehyde is formed by the dehydrogenation of methanol. The heat required for the endothermic reaction is obtained by burning hydrogen contained in the off-gas produced from the dehydrogenation reaction. The other route involves the oxidation of methanol over a catalyst of molybdenum and iron oxide. A mixture of air and methanol is vapourised and passed into catalyst-packed reactor tubes. The reaction which takes place at 350oC is highly exothermic and generates heat to provide steam for turbines and process heating. Perstorp offers a high pressure version of the Formox process which can be retrofitted to existing plants to boost capacity. The high conversion rate of the Perstorp process eliminates the need for methanol recovery via distillation and it can produce formaldehyde at concentrations up to 57%. Yields from both processes are around 90% to 92% but the oxidation route has a lower reaction temperature and the metal catalyst is cheaper than silver. However, the partial oxidation-dehydrogenation route is still the most prevalent. Though, there are several routes to manufacture formaldehyde only routes based on catalytic oxidation of methanol are being employed today. Today, all of the world's commercial formaldehyde is manufactured from methanol and air using either a silver catalyst or a metal oxide catalyst. Silver catalyst process combines dehydrogenation and oxidation to obtain formaldehyde, while metal oxide process employs an oxide catalyst for a direct oxidation route to formaldehyde. In comparison to conventional silver process which is based on incomplete conversion and distillative recovery of methanol, metal oxide process has higher yield, lower energy consumption through excess steam generation and produces highly concentrated formaldehyde solutions without distillation, allowing for low operating cost. The improved version of silver process, which employs complete conversion of methanol avoiding distillation step, has made it possible to produce formaldehyde of higher concentration with substantial reduction in energy consumption levels.

Approximately 1 million metric tons of urea-formaldehyde resin are produced annually.

More than 70% of this urea-formaldehyde resin is used by the forest products industry for a

Urea-formaldehyde resins are the most prominent examples of the class of thermosetting

resins usually referred to as amino resins.2,3 Urea-formaldehyde resins comprise about

80% of the amino resins produced worldwide. Melamine-formaldehyde resins constitute

the remainder of this class of resins, except for minor amounts of resins that are produced

from other aldehydes or amino compounds (especially aniline), or both.
