Abstract: Naphthalene sulphonic acid and formaldehyde condensation product. Title cpd. used as a stabiliser for rubber or latex, in tanning and paper manufacture and as a dispersing agent, e.g. for dyes. However, owing to SO4-- present, the dispersing power diminishes on storage. The SO4-- concn. may be reduced by neutralising the crude condensation product with NaOH, pref. adding MeOH at some stage, adjusting the concn. of the soln. to 30-65%, cooling to -10 to +23 degrees C and filtering Na2SO4 crystals.

Abstract: Spirit - soluble condensation products of phenols, formaldehyde, aromatic hydroxycarboxylic acids and/or org. anhydrides are obtained by reacting 1 mole of a (substd.) phenol(s) in aqueous soln. with 0.5-2.5 moles formaldehyde (-releasing cpds.) at elevated temp., at pH 6.5. - 14 followed by further reaction with 0.01-3 moles of an aromatic hydroxycarboxylic acid and/or 0.01-3 moles of an org. acid anhydride at 30-100 degrees C, and pH 7.5 to -1 and opt. drying and separating the condensate. Used as binders in the printing industry for the laking of basic printing inks.
