72102-47-7 - Introduction
Urea (chemical formula: nh₂ conh₂) reacts with formaldehyde (chemical formula: HCHO) or glyoxal (chemical formula: ch₂ (OH)₂) to obtain methylated products. Formaldehyde can react with urea to obtain methylurea (chemical formula: H₂ NCOCH3), and glyoxal can react with urea to obtain methylaminoethanol (chemical formula: NHCH₂ CHOH).
Methylurea is a colorless to yellow crystal with a special aroma of ammonia wine. It is soluble in water and organic solvents at room temperature, and has a high boiling point and melting point. The main use of methylurea is as synthetic materials and pharmaceutical intermediates, used in the manufacture of dyes, coatings, resins, pesticides and other chemicals.
Methylaminoethanol is a colorless to yellowish liquid with a pungent odor. It is soluble in water and organic solvents at room temperature, and has a lower boiling point and melting point. Methylaminoethanol is mainly used as an additive in industries such as water treatment, dyes and coatings, and also in the manufacture of certain drugs and surfactants.
The reaction method of formaldehyde with urea and glyoxal is relatively simple. Generally, urea or glyoxal can be reacted with an appropriate amount of formaldehyde under appropriate reaction conditions to obtain a methylated product.
In the process of operation, it is necessary to note that formaldehyde is a toxic and irritating chemical, and necessary safety measures should be taken, such as wearing protective gloves, safety glasses and protective masks, also operate in a well-ventilated environment. In addition, urea and glyoxal are also irritating and toxic and likewise require careful handling. Observe relevant safety regulations during storage and handling.
