Séparation (technologie)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The development work described in this report summarises investigations which have been undertaken with a view to optimising the solvent fractiona-tion procedures. More valid information is presented regarding the principal component types in sulphated oils i.e. neutral ofi (NO), free fatty acids (FFA) and sulpho oil or emulsifier (SO). This is used as a basis for more detailed separations of the main fractions into individual identifiable components. Note de contenu : - Separation of the sulphated and non-sulphated material
- Separation of the unsulphated oil into neutral fats and fatty acids

InflammabilitéIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The influences of seven kinds of oils on the flammability of pig chrome leather have been studied. The flammability of the fatliquored leathers was evaluated by the vertical flame test and Oxygen Index Test. The results show that the 7 oils increase the fire resistance of leather. The effect is especially shown by sulphated oils which have a more apparent effect than sulphited oils. The leathers which were fatliquored with sulphited fish oil, sulphated neatsfoot oil and lecithin have a stronger glow resistance than the leathers either not fatliquored or treated with other oils. The results should supply a basis for the preparation of fire-resistant leather.

Titre : Provisional method for the determination of un-neutralised free fatty acid in sulphated oils-SLO 2/17 Type de document : texte imprimé Auteurs : E. A. Taylor, Auteur Année de publication : 1975 Article en page(s) : p. 29 Langues : Anglais (eng) Catégories : Acides gras

Huiles sulfatéesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The method determines that portion of free fatty acid present in the oil after sulphation, and which is in excess of the neutralising base. It is thus complementary to method SLO 2/16 which determines the total free fatty acid due to hydrolysis. The method applies particularly to ammonia or amine neutralised sulphated oils which will not titrate by the simple method SLO 2/5. Such samples are often unstable and lose ammonia fairly rapidly on standing. The method determines the un-neutralised free fatty acid at the time of the test and should be repeated if the result is required again later. Note de contenu : - Principle
