| titleOfInvention | Organosilicon carbamyl compounds and process for producing the same |
| abstract | Organosilicon compounds containing a carbamylalkylsilyl grouping of the formula <FORM:0882059/IV (a)/1> where R and R1 are hydrogen, alkyl, aryl or substituted alkyl or aryl groups, and a is at least 2, are prepared by reacting a compound containing the grouping <FORM:0882059/IV (a)/2> where M is halogen, hydroxy or the group OR11 where R11 is alkyl or aryl, with a compound RR1NH. The products which are claimed are those of the above formula in which the remaining valencies of the silicon are attached to R11bX3-b\t radicals, X being alkoxy, and include silanes and polysiloxanes. The preferred starting materials are esters of carboxyalkylalkoxysilanes, and carboxyalkylpolysiloxanes and their ester and halide derivatives, and include low cyclic polymers and copolymers. These are described in Specifications 882,094 and 882,095. The nitrogen compounds are ammonia or primary or secondary amines and the substituents in the R and R1 groups may be nitro, amino, hydroxy, alkoxy, halo, carboxy, carbalkoxy or carbaryloxy. Examples of amines are methylamine, aniline, p-aminobenzoic acid, n-butylamine, propylene diamine, dimethylamine, methyl phenyl amine, diphenyl amine and phenylethylamine. The reaction may be effected in an organic liquid. Hydrogen halide acceptors such as tertiary amines may be present where appropriate. The examples describe the preparation of (1) beta-(N - p - carboxyphenyl)carbamylethyltriethoxysilane; (2) beta-(N-n-butyl)carbamylethyltriethoxysilane; (3) beta-(N-phenyl)carbamylethyltriethoxy; (4) gamma-(N-3-aminopropyl)carbamylpropylmethyldiethoxysilane; (5) gamma-carbamylpropylmethyldiethoxysilane; (6) and (7) a Me3SiO- end-blocked dimethylsiloxane oil containing gamma-carbamylpropylmethylsiloxane units; (8) a Me3SiO- end-blocked oil containing gamma-(N-2-aminoethyl)carbamylpropylmethylsiloxane; gamma-carboxypropylmethylsiloxane and dimethylsiloxane units. Uses: The compound in Example 1 is an absorber of ultra-violet light. Other compounds:-additives to thermosetting resins and other polysiloxanes, adhesives, sizes for fibrous materials particularly glass. |
