Abstract: Solvent-stable forms of metal-free phthalocyanine alpha and gamma modifications (prepared by a method involving partial chlorination in a fluidized bed of the solvent-unstable forms (see Group IV (c)), are made into intaglio printing or spraying lacquers.  In examples: (1) the esterification product of a colophonymaleic acid adduct with pentaerythritol and glycerine are dissolved in xylene, a phthalocyanine as above is added, and the mixture ball-milled to give an intaglio printing lacquer; (2) an adduct of linseed oil and an esterification product of phthalic acid and a mixture of glycerine and pentaerythritol are dissolved in xylene, titanium dioxide and a phthalocyanine as above are added, and the mixture is funnelmilled, dried, and cobalt, manganese, and lead salts are added to give a spraying lacquer.ALSO:Alpha and gamma modifications of metal-free phthalocyanine which are stable to organic solvents are made by (1) grinding the solventunstable form of one of said modifications with an inorganic substrate which is stable to chlorine; (2) chlorinating the resulting mixture in a fluidized bed at 0-100 DEG  C. at a speed of flow of 4-40 litres per square centimetre per hour up to a chlorine content of the phthalocyanine of 1-10 per cent; and (3) finely subdividing the product after removal of the substrate and ingredients of the bed.  Before step (3), an amount of the corresponding solventunstable form may be added such that the total chlorine content is 1-3 per cent.  The dyestuff to substrate weight ratio may be 1 : 2 to 1 : 10, the substrate may be sodium chloride or sulphate, and the ground dyestuff-substrate mixture from step (1) may be mixed with up to five times the amount of a more coarsely-ground inorganic substrate stable to chlorine to give a mixture which may be fluidized well.  The chlorine may be diluted with an inert gas.  If the alpha modification obtained contains any beta form, this may be eliminated by swelling in 62 per cent sulphuric acid.  The products are suitable for intaglio printing or spraying lacquers (see Group IV (a)).  Examples describe the stabilization of alpha and gamma forms using sodium chloride or sulphate as substrate.

Patent GB-907664-A (GB)
Title: Lubricant material
IPC: C07F7/22
Filed: 1958-12-16
Abstract: A lubricant material contains an oleoginous lubricant base together with (a) a dialkyl tin sulphide compound of formula <FORM:0907664/III/1> wherein R1 and R2 are the same or different alkyl groups containing 3-6 carbon atoms or (b) a trimeric tin sulphide compound of formula <FORM:0907664/III/2> wherein the R1s are methyl or ethyl groups or hydrogen.  The lubricant base may be chosen from hydrocarbon oils (e.g. petroleum or polyolefin oils), organosilicon compounds (e.g. polysiloxanes, halogen-substituted polysiloxanes or silicate esters), polyesters (e.g. dialkyl esters of dicarboxylic acids, complex esters, esters formed between polycarboxylic acids and mono- or poly-hydric alcohols, or esters formed between monocarboxylic acids and polyhydric alcohols), fluorocarbon or chlorofluorocarbon oils, aromatic ether oils (which may be halogen-substituted), phosphate esters, tetrahydrofuran/alkene oxide copolymers, polyalkylene glycols or their esters or ethers, polyglycidyl ethers and polythioglycols.  The lubricant material may contain additional ingredients such as soaps (e.g. lead oleate, aluminium tristearate, lithium naphthenate or barium oleate), antioxidants or other thickeners, and may be used as a lubricant in electric equipment or as a cutting oil.  Where the lubricant material is a grease, it may contain unreacted fat, fatty acids and alkali; unsaponifiable matter including glycerol and fatty alcohols; rosin or wool grease; water; and modifiers or peptizers.  In use, the lubricant material may be placed between the rubbing surfaces, the surfaces allowed to rub together at a low initial load while in contact with the lubricant material, and the load gradually increased up to the operating load.  In this way, an anti-wear film is believed to be formed on the rubbing surfaces.  Alternatively, a break-in lubricant (comprising an organometallic compound of a Group IIIa or IVa metal and a mineral oil) may first be placed between the rubbing surfaces, the surfaces allowed to rub together lightly while in contact with the break-in lubricant, and the break-in lubricant then removed and replaced by the lubricant containing the tin sulphide compound. In the examples, (1) diisopropyl tin sulphide is added to a grease prepared from mineral oil, 12-hydroxy stearic acid, boric acid and quicklime, (2) di-n-butyl tin sulphide is added to a grease prepared from mineral oil, blown asphalt, hydrogenated fish oil fatty acids and litharge, (3)2,2,4,4,6,6-hexamethyl-1,3,5,2,4,6-trithiatristanninane is added to mineral white oil and (4) 2,4,6-triethyl- 2,4,6-trimethyl-1,3,5,2,4,6,-trithiatristanninane is added to a mixture of the o-, m- and p-isomers of bis-(methylphenoxy) benzene.
