Filed: 1927-11-18
Abstract: 312,372. Armstrong, J. J. V., (Plauson, G.). Nov. 18, 1927. Pitch and tar.-Tar is hardened by dispersing therein substantial quantities of hard pitch, bitumen, or natural resin by the aid of a synthetic resin as dispersator. The synthetic resins, for instance phenol aldehyde resins and cumarone resins, may be added as such or may be formed within the mass, for instance by the action of aldehydes on phenol contained in the tar, or in the case of cumarone resins by the action of known condensing agents on solvent naphtha. The resulting products may be used for road making. In examples (1) 100 parts of coal tar are melted with 5 to 50 parts of phenol aldehyde resin in the A or B state, and pitch is added; further additions of from 5 to 3 per cent of oils, factis or rubber solution may be made. (2) 200 parts of crude tar, 10-20 parts of solvent naphtha and 2-3 per cent of concentrated sulphuric acid are heated to 30-60‹ C. until cumarone resin formation is complete; the residual acid is neutralized by calcium hydroxide and 500-600 parts of hard pitch are added and thoroughly incorporated in a colloid mill; the injurious ingredients such as phenols and cresols may be combined with aldehydes.

Title: Oxygen containing propene derivatives
Inventor: HALL REGINALD HAROLD
Filed: 1950-12-23
Abstract: 1 : 3-Dihydroxypropene derivatives of the general formula R3O-CH2-CR6=CH(OR4) and acrolein derivatives of the general formula CH2=CR6-CH(OR4) (OR5) are manufactured by pyrolysing propane derivatives of the general formula R3O-CH2-CHR6-CH(OR4) (OR5) (wherein R3, R4 and R5 represent alkyl, aryl aralkyl, cycloalkyl or acyl radicals, R4 and R5 being identical and at least one of R3, R4 and R5\h representing an acyl radical, and R6 represents hydrogen or an alkyl radical) at 200-450 DEG  C., preferably 325-425 DEG  C.  The process is preferably effected in a homogeneous gas phase in the presence of an acidic cracking catalyst (e.g. sulphuric acid, sulphur trioxide, hydrogen chloride, di-isopropyl sulphate, dimethyl sulphate or ethyl hydrogen sulphate).  There may alternatively be used non-acidic cracking catalysts (e.g. quinoline) or heterogeneous cracking catalysts (e.g. acid-treated clays, aluminium phosphate, alumina or silica gel, alone or in association with an alkaline-earth metal oxide or hydroxide).  It is expedient to carry out the pyrolysis and subsequent distillation in the presence of a stabilizing agent such as an amine, preferably a high boiling tertiary amine (e.g. pyridine, quinoline or collidine).  The relative proportions of the two pyrolysis products may be varied by controlling the reaction conditions (e.g. temperature and contact time), and if one is unwanted it may be reconverted to the starting material by reaction with the appropriate hydroxy or carboxy compound, e.g. at room temperature in the presence of an acid catalyst.  The 1 : 3-dihydroxypropene derivatives may be hydrogenated to the corresponding 1 : 3-propylene glycol derivatives, which are useful as solvents.  Examples describe the pyrolysis under various conditions of 1 : 1 : 3-triacetoxypropane to acrolein diacetate and 1 : 3-diacetoxypropene.  The latter on hydrolysis with very dilute aqueous hydrochloric acid and addition of 2 : 4-dinitrophenylhydrazine yields 3-acetoxypropanal 21 : 41-dinitrophenylhydrazone, and it may also be hydrogenated in ethyl acetate to 1 : 3-diacetoxy propane.  Additional starting materials specified are 1 : 1 : 3 - triacetoxy - 2 - methylpropane, 1 : 1-dimethoxy-, -diethoxy-, -dipropoxy-, -dibenzyloxy- and -dipropionoxy-3-acetoxypropane, and 1 : 1-diacetoxy-3-phenoxy-, -methoxy- and -ethoxy-propane.  Still further radicals which may be represented by R3, R4 and R5 are butyl, tolyl, xylyl, cyclopentyl, cyclohexyl, butytyl and benzoyl.  Specification 695,789 is referred to.
