Patent GB-597627-A (GB)
Title: Methods for the preparation of sulphonaphthenic derivatives of albumins
IPC: C08L89/00
Filed: 1940-02-12
Abstract: Sulphonaphthenic derivatives of albumins are prepared by treating naturally occurring or artificially prepared aqueous solutions of albumins with a sulphonation product of crude petroleum naphtha, or fractions thereof, containing naphthenic hydrocarbons and removing the resulting product.  Preferably, the aqueous albumin solution is first acidified, to an extent insufficient to precipitate the albumin, whereby the amount of sulphonated naphthenic hydrocarbon required is reduced.  Albumin solutions mentioned are blood in the whole, defibrinated or separated form and glutin solutions and in the latter case separation of several fractions of glutin derivatives is possible. The products are soluble in alkali and react with organic bases; they may be used in glues (see Group V) and as fillers in plastics, especially in phenolformaldehyde plastics.  Examples describe the preparation of sulphonaphthenic derivatives of blood by treating blood, alone or acidified with sulphuric or acetic acid, with an aqueous solution of sulphonated naphthenic hydrocarbons and removing the precipitated product.ALSO:Sulpho-naphthenic derivatives of albumins, for example, of blood and glutin may be used in the preparation of adhesives, especially for ply-wood.  The manufacture of the sulphonaphthenic compounds is described (see Group IV).
