Title: Compounds having a retarding action on the coagulation of blood and processes of preparing the same
IPC: C08B37/02
Filed: 1944-10-27
Abstract: Sulphuric acid esters of dextrane are prepared by subjecting dextrane, which may be partially hydrolysed, to the action of a sulphating agent, for example sulphur trioxide, concentrated sulphuric acid, oleum, sulphuryl chloride, N-pyridinium sulphonic or, preferably, chlorsulphonic acid.  The esterification may vary from less than one esterified OH-group per glucose unit up to complete esterification.  The acid esters may be partially or completely neutralized by means of a basic compound, preferably by alkali or alkaline earth bases.  The salt or ester may be freed of sulphuric acid by dialysis, by precipitation of the salt or ester from aqueous solution with alcohol or by precipitating the sulphuric acid by means of Ca or Ba ions.  The salts or esters may be used as anti-coagulating agents in the treatment of blood (see Group VI).  In an example, a partially hydrolysed dextrane, prepared by boiling a 4 per cent aqueous dextrane solution with hydrochloric acid for 3 minutes followed by neutralization with caustic soda and precipitation as the sodium salt by addition of alcohol, was reacted with chlorsulphonic acid in anhydrous pyridine and the resulting sulphuric acid ester of dextrane precipitated by addition of alcohol. The ester was then dissolved in water, neutralized with caustic soda, the solution dialysed until free of sulphuric acid after which the sodium salt of the ester was precipitated by addition of alcohol.  A suitable partially hydrolysed dextrane may also be of the kind disclosed in Specification 583,378.ALSO:In an example, a partially hydrolysed dextrane is prepared by boiling an aqueous solution of dextrane with concentrated hydrochloric acid for 3 minutes, the solution then being cooled and neutralised with caustic soda; the partially hydrolysed dextrane obtained is precipitated by addition of alcohol. Reference is made to the preparation of such dextrane disclosed in Specification 583,378, [Group IV].ALSO:Sulphuric acid esters of dextrane in the neutralised or unneutralised state (see Group IV) may be employed as agents for retarding the coagulation of blood.  Preferably the esters are derived from partially hydrolysed dextrane of the kind disclosed in Specification 583,378 (as open to inspection under Sect. 91) [Group IV].  Salts of these esters, particularly of alkali or alkaline earth metals in water, saline solutions or other therapeutic fluids yield alone or in admixture with other physiologically suitable salts and therapeutic substances, solutions well adapted for intravenous injection.  The degree of esterification of the dextrane may vary from a sulphur content below that of the mono-ester up to complete esterification while p  the neutralisation may be partial or complete.  An example describes the preparation of the sodium salt of the sulphur ester of a partially hydrolysed dextrane.

Abstract: 1519128 Separating the products of the hydrogenation of coal SAARBERGWERKE AG 20 May 1977 [22 May 1976] 21270/77 Heading C5E A method of separating a residue containing solids from a liquid fraction produced by the hydrogenation of coal or like carbonaceous material under high pressure and at a high temperature, which liquid product fraction has already been freed from relatively low-boiling point components, comprises the steps of reducing the pressure on said product fraction in at least two stages, a first stage in which the pressure is reduced in an expansion engine with the production of external work, and in a following stage or stages in which the pressure is further reduced by passage through an expansion valve, and thereafter subjecting the product fraction to a phase separation to separate a residue containing solids therefrom. The work produced in the expansion engine may be used in a pumping stage in the hydrogenation process.
Patent GB-243470-A (GB)
Title: Improvements in and relating to synthetic resin composition
IPC: C08G8/06
Filed: 1924-09-09
Abstract: Synthetic resins, suitable for use in moulding gramophone records, printing plates and other articles, are prepared by condensing a phenol, such as phenol, cresol, resorcinol or naphthol, with furfural or furfuramide to obtain a fusible resin which is subsequently hardened by means of a furfural or a methylene hardening agent, or alternatively by condensing the phenol with formaldehyde, acetaldehyde or paraldehyde in the usual manner and hardening this resin with furfural or furfuramide.  The condensation may take place with or without a catalyst, acid or basic, such as hydrochloric acid or potassium carbonate, and the fusible resin may be mixed prior to hardening with fillers such as pigments, dyes, or corn-cob cellulose. The resins produced are jet black without addition of any pigment and may furthermore be removed hot from the mould without impairing their glossy appearance.  In examples, phenol crystals and furfural are condensed in presence of hydrochloric acid at about 200 DEG  F., the water and excess phenol boiled off and the fusible resin hardened with furfural, furfuramide or hexamethylenetetramine in presence or absence of a solvent such as alcohol or acetone; the fusible resin from phenol and formaldehyde or from phenol and acetaldehyde or paraldehyde and hydrochloric acid is hardened with furfural or furfuramide; phenol is condensed with an equal quantity of furfural in an autoclave at 420-450 DEG  F. to produce a partially-reacted product which may be hardened by heat and pressure or may be mixed with fillers and a solvent, or if a smaller amount of furfural be employed a fusible resin is obtained which may be hardened with furfural or hexamethylenetetramine; phenol is condensed with furfural at 250-350 DEG  F. in presence of potassium carbonate under pressure or not and the product mixed with fillers and hardened. p-Phenylenediamine may be used to accelerate the hardening process. Reference has been directed by the Comptroller to Specification 187,480.
