4-Aminophenol (or para-aminophenol or p-aminophenol) is an organic compound with the formula H 2 NC 6 H 4 OH. Typically available as a white powder, [ 3 ] it is commonly used as a developer for black-and-white film , marketed under the name Rodinal .
Like other hydroxylamines it will react with aldehydes to form nitrones, illustrative is the condensation with benzaldehyde to form diphenylnitrone, a well-known 1,3-dipolar compound: [4] C 6 H 5 NHOH + C 6 H 5 CHO → C 6 H 5 N(O)=CHC 6 H 5 + H 2 O. Phenylhydroxylamine is attacked by NO + sources to give cupferron: [5] C 6 H 5 NHOH + C 4 H 9 ...
The three aminophenol isomers: Left: 2-Aminophenol (o-aminophenol) Center: 3-Aminophenol (m-aminophenol) Right: 4-Aminophenol (p-aminophenol) Aminophenol may refer to any of three isomeric chemical compounds: 2-Aminophenol; 3-Aminophenol; 4-Aminophenol; They are simultaneously an aniline and a phenol

The salted green cheese curd is put into cheese moulds lined with cheesecloths and pressed overnight to allow the curd particles to bind together. The pressed blocks of cheese are then removed from the cheese moulds and are either bound with muslin-like cloth, or waxed or vacuum packed in plastic bags to be stored for maturation. Vacuum packing ...
The curd is cut into 6-to-16-millimetre (1 ⁄ 4 to 5 ⁄ 8 in) cubes using stainless steel wire knives. A smaller cube size means the cheese will be lower in moisture, whereas a larger cube size will result in a high-moisture cheese. It is important that cutting time is minimized and that the cuts be clean.
Cheese ripening, alternatively cheese maturation or affinage, is a process in cheesemaking. It is responsible for the distinct flavour of cheese, and through the modification of " ripening agents ", determines the features that define many different varieties of cheeses, such as taste, texture, and body.
