Furaldehydes

Formaldehyde ( for-MAL-di-hide, US also fər-) (systematic name methanal) is a pungent colorless gas mainly used in the production of industrial resins, such as for particle board, coatings, plastics, pulp, paper, synthetic fibers, and textiles. A ~5% solution in water of formaldehyde is used as a disinfectant and fumigant in industrial, agricultural, and healthcare settings, and a ~37% solution is used to preserve tissue samples in labs. In 2024, the global production of formaldehyde was estimated at 26 million tons per year, and is a precursor to many other materials and chemical compounds. It is an organic compound with the chemical formula CH2O and structure H2C=O Wikipedia

IB2 Authorized IBCs: Metal (31A, 31B and 31N); Rigid plastics (31H1 and 31H2); Composite (31HZ1). Additional Requirement: Only liquids with a vapor pressure less than or equal to 110 kPa at 50 °C (1.1 bar at 122 °F), or 130 kPa at 55 °C (1.3 bar at 131 °F) are authorized.

The maximum degree of filling must not exceed the degree of filling determined by the following: Where: tr is the maximum mean bulk temperature during transport, tf is the temperature in degrees celsius of the liquid during filling, and α is the mean coefficient of cubical expansion of the liquid between the mean temperature of the liquid during filling (tf) and the maximum mean bulk temperature during transportation (tr) both in degrees celsius. b. For liquids transported under ambient conditions α may be calculated using the formula: Where: d15 and d50 are the densities (in units of mass per unit volume) of the liquid at 15 °C (59 °F) and 50 °C (122 °F), respectively.
