Title: Water dilutable surface coating alkyd resins
Inventor: WILLIAMS PARRY
IPC: C08G63/668
Filed: 1963-12-21
Abstract: Water-dilutable alkyd resins have a backbone comprising residues of polyols, of which at least 90% by weight are residues of hindered diols, and polycarboxylic acids having at least three carboxyl groups per molecule, the resin also containing residues containing b g -ethylenically unsaturated ether groups, and sufficient carboxyl groups to render the resin water dilutable. The hindered diols have at least three carbon atoms, a carbon atom next to each carbon atom carrying the hydroxyl groups being fully substituted by alkyl, aryl or aralkyl groups, preferably C1- 4 alkyl groups, and may be e.g. neopentyl glycol, 2-methyl-2-ethyl-propane-1,3-diol, 2,2 - diethylpropane - 1,3 - diol, 2,2 - dimethylpentane-1,3-diol 2,2-dimethylbutane-1,3 - diol and 2,2,4 - trimethylpentane - 1,3-diol. Suitable polycarboxylic acids are trimellitic, trimesic, hemimellitic, pyromellitic, tricarballylic and camphoronic acids. The unsaturated groups may be derived from mono- or polyhydric alcohols containing at least one b ,g -ethylenically unsaturated ether group, e.g. the monoallyl and diallyl ethers of glycerol, trimethylol ethane and trimethylol propane, and the monoallyl, diallyl and triallyl ethers of pentaerythritol, and the corresponding methallyl compounds.  The resins have acid values of at least 30, preferably 50 to 100.  The polycarboxylic acids and hindered diols may be replaced by up to 50 mol. per cent of mono- and dibasic acids, e.g. phthalic or maleic acid, and up to 10 wt. per cent of other polyols, respectively. The resin may also contain residues of saturated or unsaturated fatty acids, e.g. dehydrated castor oil acids.  It may be prepared by partially esterifying the polycarboxylic acid with the unsaturated ether alcohol, esterifying the resulting ester having at least two free carboxyl groups per molecule, with the hindered diol, and further esterifying the product with more polycarboxylic acid. Fatty acid residues may be introduced at the same time as the hindered diol  The polycarboxylic acids are preferably used as anhydrides.  The resin is dissolved or dispersed in water or water containing a water-miscible organic solvent, e.g. ethanol, propanol or butanol, or the methyl, ethyl or butyl mono-ethers of ethylene glycol, in the presence of a base, which is preferably volatile, e.g. ammonium hydroxide or a volatile amine, e.g. triethylamine, to give a solution or emulsion which may be diluted with water.  In examples, 1 mol. of trimellitic anhydride is reacted with 1 mol. of trimethylol propane diallyl ether to an acid value of 276, then esterified with 2 mols. of neopentyl glycol and 0.75 mols. of dehydrated castor oil fatty acids to an acid value of 5-10, and finally reacted with 0.5 or 0.54 mols. of trimellitic anhydride to an acid value of 64. The resins were dissolved in water containing triethylamine and a cobalt drier, and used to make surface coatings.

Title: Process and apparatus for the recovery of formaldehyde
IPC: B01D5/00
Filed: 1965-12-20
Abstract: Formaldehyde is separated from a gaseous mixture containing formaldehyde, water vapour and gases, such as oxygen and nitrogen, by passing the gaseous mixture in indirect heat exchange with a coolant to condense and solidify the major proportion of the formaldehyde as paraformaldehyde and to condense a portion of the water vapour, separating the depleted gaseous mixture from the paraformaldehyde and condensed water, and then heating the paraformaldehyde and water together by indirect heat exchange to form an aqueous solution of formaldehyde.  The formaldehydebearing gaseous mixture may be produced by a vapour-phase methanol oxidation plant employing air as oxidizing agent and a ferric oxide catalyst.  The process may be carried out in an apparatus comprising two heat-exchangers associated with a system of valves whereby the flow of gaseous mixture may be switched from one heat-exchanger to the other so that the condensation of formaldehyde and water may take plac in one heat-exchanger while the paraformaldehyde and condensed water (formed in the previous cycle) are heated together in the other heat-exchanger (see Division B1).  The depleted gaseous mixture may be scrubbed with water to recover residual formaldehyde.
