Title: A new substituted aminopropane diol and processes for its preparation
Filed: 1951-02-12
Abstract: The invention comprises DL-erythro 2-o-carboxybenzamido - 1 - p - nitrophenylpropane - 1 : 3-diol, and the manufacture thereof by condensing p-nitrobenzaldehyde with a -phthalimidoacetaldehyde in the presence of a basic condensing agent to produce a compound having a melting-point between 145 DEG  and 185 DEG  C., reducing this by known methods for the reduction of an aldehyde group to an alcohol group without affecting a nitro group, and hydrolysing the product under alkaline conditions.  The condensation may be effected in an anhydrous organic solvent (e.g. dioxane or pyridine) at 0-25 DEG  C. in the presence of a strong organic base (e.g. piperidine, preferably in the form of its acetate, or a strong tertiary amine free from hydroxy groups, such as triethylamine), and the reaction conditions are preferably chosen so that the condensation product (which is probably an addition product of the compound of the formula <FORM:0685021/IV (b)/1> with a -phthalimidoacetaldehyde) has a melting-point between 150 DEG  and 170 DEG  C.  The reduction of this compound to 2-phthalimido-1-p-nitrophenylpropane-1 : 3-diol may be effected by the Meerwein method using an oxidizable aluminium alkoxide (preferably derived from a secondary aliphatic alcohol) or by means of an alkali metal borohydride (advantageously at 10-50 DEG C. in an organic solvent, preferably methanol, dioxane or dimethylacetamide).  The hydrolysis is conveniently effected with dilute aqueous caustic soda, after which the reaction mixture may be extracted with ether and the aqueous phase acidified to precipitate the desired product.  In examples, the reduction step is effected by means of: (1) and (2) aluminium isopropoxide in isopropanol; (3) sodium borohydride; (4) potassium borohydride.
Patent GB-397137-A (GB)
Title: Improvements in yarn manufacture
IPC: D01F2/28
Filed: 1932-02-05
Abstract: Yarns, particularly yarns of cellulose acetate or other organic derivatives of cellulose, having the appearance of spun yarn, that is yarn made from staple fibre, are produced by subjecting a bundle of filaments in a softened state to an operation such as stretching, whereby individual filaments are broken.  As described, the yarn is stretched, subsequently to manufacture and with or without previous twisting, to such a degree that the main filament bundle does not break and, to ensure that as many ends as possible are broken, it is desirable to stretch to such an extent that a reduction in denier takes place: for example, threads of acetone-soluble cellulose acetate may be softened in 40-50 per cent dioxane, or an equivalent concentration of diacetone alcohol, ethyl lactate, glycol monoacetate, methyl glycol monoacetate or the like and stretched to 300-500 per cent.  The stretching may be effected by two or more rollers rotating at different speeds and may take place while the yarn is in hank form, or while it is travelling, for example, from a yarn package to a winding-device, or from a spinning-machine to a winding-device, or filaments in warp formation may be stretched and a number of bundles, for example, five to ten or more, may be associated continuously with the stretching and twisted, or stretching may take place during the manufacture of the filaments. In wet spinning the filaments may be stretched and broken in the coagulating bath, suitable baths for producing filament bundles of low denier being described in Specifications 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 371,360, 375,423, and 380,819. The yarn may be treated to lay the projecting ends and subjected to a gassing operation.  Preferably the final twisting is effected in the presence of a softening-agent, for example, by means of a Topham box, whereby a more crinkled yarn is obtained.  The yarn may be doubled with any other yarn and with one or more broken filament yarns.  The basic yarn may be of high, medium or low lustre.  Any after treatment to modify the appearance or properties of the yarn may be applied, for example the yarns may be treated with shrinking-agents as described in Specifications 380,504, 380,505, and 389,823.  The yarns may be introduced into the warp or weft or both of woven fabrics to produce the appearance of a fabric composed of staple fibre yarns, or to produce pattern effects, and may be used as effect material or the sole or principal constituent of knitted fabrics.
