Title: New quaternary ammonium compounds related to reserpine and process for their manufacture
IPC: C07D459/00
Filed: 1956-04-09
Abstract: The invention comprises tetradehydro-reserpic acid of the formula <FORM:0822723/IV (a)/1> and its salts, esters and O-acylated esters. These are made from reserpic acid, reserpic acid esters, O-acylated reserpic acid esters and the corresponding 3-iso-compounds (or salts thereof) by treatment with an oxidising agent having a potential of - 1.7 volts or higher, e.g. lead tetraacetate, lead dioxide in acetic acid, maleic acid and palladium black, or oxygen in acetic acid with a platinum catalyst.  The catalytic methods are preferred for dehydrogenating the free acid.  The products may be modified as follows: free acids converted into salts with bases; esters converted by alkaline hydrolysis or by alcoholysis to the free hydroxy-esters or to the hydroxy-acids; free carboxylic groups esterified with a diazoalkane or with an alkanol and acid catalyst; free hydroxyl groups esterified with an acid halide or anhydride; any of the above converted into salts with acids. Examples show the dehydrogenation of (1) reserpine with lead tetra-acetate in acetic acid; product is obtained as hydrochloride and can be hydrolysed to methyl tetradehydro-reserpate and tetradehydro-reserpic acid (hydrochloride); (2) methyl reserpate with lead tetra-acetate in acetic acid; product is obtained as hydrochloride and may be esterified to give tetradehydro-reserpine; (3) reserpic acid hydrochloride with maleic acid and palladium black; product (hydrochloride) can be esterified with diazomethane; (4) 3-iso-reserpine with lead tetraacetate in acetic acid; product is obtained as hydrochloride.  3-Iso-reserpic acid and methyl 3-iso-reserpate can be dehydrogenated similarly.  The iso-compounds used as starting materials are prepared as follows: iso-reserpine from reserpine and acetic anhydride, methyl iso-reserpate from methyl reserpate and toluene-p-sulphonic acid, and iso-reserpic acid by hydrolysis of the latter.  Reserpic acid itself and its esters are described in Specification 744,290.  The tetradehydro compounds can be reduced with sodium borohydride to the corresponding 3-isoreserpic acid derivatives.ALSO:Sunscreen compositions contain tetradehydroreserpic acid of the formula <FORM:0822723/VI/1> or its salts, esters and O-acylated esters, particularly tetradehydro-reserpine hydrochloride.  They may be incorporated in hydrophilic ointments containing, e.g., propylene glycol, stearyl alcohol and petroleum jelly, or they may be used as solutions in 70% alcohol.

Patent GB-1037381-A (GB)
Title: Producing artificial filamentary material from condensation polymers
IPC: D01F6/72
Filed: 1963-03-20
Abstract: In the production of artificial filaments by wet-spinning a solution in sulphuric acid of at least 75% concentration by weight of a condensation polymer containing repeating =NCO- groups, the filaments are stretched to increase their length by at least 10% before drying them and while they are still plastic and are subsequently, if necessary after washing free from sulphuric acid, dried while in a substantially tensionless condition, whereby the filaments develop a crimp during the drying step.  The filaments may be stretched to increase their length by from 10 to 150%.  The polymer may be a nylon, a polyurethane or a polyurea.  The process is particularly suitable for the production of crimped filaments of polymers whose melting points are too high to enable melt spinning to be used. These polymers include, in general, polymers having cyclic groups in the molecule, e.g. meta- or paraphenylene, cycloalkylene groups such as 1,4-cyclohexylene and/or heterocyclic groups such as piperazylene or 2,5-dimethyl piperazylene, as an integral part of the polymer chain. The polymer used in the examples is polyhexamethylene terephthalamide.  The concentration of the sulphuric acid used in preparing the spinning solutions is preferably 95 to 100% by weight. Fuming sulphuric acid containing up to 7% or more by weight of free sulphur trioxide may also be used.  The coagulant is preferably sulphuric acid of 40 to 60% concentration. The undried filaments may be stretched in the coagulating bath or after removing the filaments from the bath.  In the latter case they may be stretched in a bath of hot water or in aqueous sulphuric acid (of about 50% by weight concentration) at about 50 DEG  C.  The filaments may be dried by floating them in a stream of warm air, e.g. by passing the filaments and air through a tunnel or long shoot, or by collecting a skein of the wet filaments on the surface of a porous belt or screen and exposing the skein to warm air.  The yarn may be dried in the form of continuous filaments or the wet tow may be cut into staple lengths and then dried.  In the case of a tow of continuous filaments, the filaments may be dried on a heated tapered thread advancing reel or a set of tapered skewed or canted steam heated rolls.  The taper allows full shrinkage to occur during the drying step. The temperature of the air or heated surfaces used in the drying step may be about 50 DEG  to 175 DEG  C. and the residual moisture in the filaments after drying not more than about 6%. The filaments after the stretching step and before being dried may be contacted with an inert gas or liquid at 60 DEG  to 180 DEG  C., preferably water at 100 DEG  C., for a period of 2 to 15 minutes.  Alternatively, the heat treatment may be carried out on filaments which are already crimped as a result of having been dried free from tension.  In either case the treatment improves the tensile strength of the filaments and in the latter case sets the crimps and increases their number per inch of filament.
