  • Patent number: 4230824
    Abstract: The invention provides a means for making a high functional (.gtoreq.6.5), low viscosity, low hydroxyl number sucrose-based polyether polyol. The process involves the use of a polyalkylene polyamine, such as diethylenetriamine, as both co-initiator and catalyst for the alkoxylation reaction of sucrose. These polyols are particularly suited for the production of rigid polyurethane foams having excellent dimensional stability, particularly at low temperatures.

  • Patent number: 4223129
    Abstract: A continuous process for making alkyl aldosides from polysaccharides and more particularly mixed alkyl glycosides from starch by direct alcoholysis. A polysaccharide, such as starch, is slurried in an alcohol and passed through a heated, confined zone under pressure in the presence of an acid catalyst to form a mixed alkyl aldoside. The alcohols which may be used include methanol, ethanol, propanol and butanol, their isomers and mixtures thereof. Higher alkyl glycosides are surfactants and, in some instances, it is advantageous to use higher alcohols, such as decyl and dodecyl alcohols, to obtain particular surfactant properties in the resulting alkyl glycosides. Mixed alkyl glycosides are useful in detergent applications, and as backbone polymers in polyurethane foams.

  • Patent number: 4166172
    Abstract: An improved method for the production of polyether polyol compositions is disclosed wherein a polyhydric initiator is oxyalkylated with alkylene epoxides at lower temperatures in the presence of an aqueous ammonia solution. The polyether polyol compositions produced have desirable hydroxyl numbers and low viscosities and are particularly useful in the production of excellent rigid polyurethane foams. In addition to catalyzing the reaction, the nitrogen containing moiety itself undergoes oxyalkylation during the process such that the polyether polyol compositions produced contain, admixed therewith, various alkoxyalkanol amines. The alkoxyalkanol amines having reactive hydroxyl groups and acting as a mild catalyst for the polyolisocyanate reaction need not be removed from the polyether polyol composition. In addition, the alkoxyalkanol amines increase the blending compatibility of the polyether polyol compositions.

  • Patent number: 4024290
    Abstract: The present invention encompasses a bulking agent suitable for incorporating into formulated foods. The bulking agent of the present invention is prepared by condensation of glucose and sorbitol in the presence of an acid-ion exchange resin. The bulking agent of the present invention provides the functions and bulk of about the same weight of sucrose when incorporated into formulated foods. The bulking agent of the present invention is most advantageously used in conjunction with high intensity sweeteners.

  • Patent number: 4017608
    Abstract: The invention provides a novel therapeutic composition comprising a pharmaceutically acceptable carrier containing a therapeutically effective amount of an ethereal monosubstitution of a monosaccharide derivative having the general formula S-O-Y, wherein S is the residue of the monosaccharide derivative selected from the group consisting of pentoses, hexoses and heptoses as single or polysubstituted acetals, ketals or esters and Y is selected from the group consisting of cyclic monovalent nitrogen-containing organic radicals and residua and monovalent organic radicals and residua having the general formula ##STR1## wherein R.sub.1 is a divalent organic radical having a linear carbon chain length of about 1-7 carbon atoms and R.sub.2 and R.sub.3 are selected from the group consisting of --H, --OH, --SH; halogen and monovalent organic radicals and residua having a linear carbon chain length of about 1-7 carbon atoms.

  • Patent number: 4011389
    Abstract: To obtain nonionic surfactants having solubility and stability in relatively strong aqueous solution of caustic, salt or other electrolytes, corn starch or a similar source of glucose units is reacted with an alcohol containing up to about 4 carbon atoms to obtain a glycoside somewhat more lipophilic than the saccharide, and then the resulting glycoside is reacted with a hydrophobic oxirane-containing material such as a C.sub.6 to C.sub.18 epoxyalkane or a glycidyl ether having about the same number of carbon atoms.
