摘要:
A spermicidally active suppository comprising an alkylphenoxypolyethoxyethanol as the spermicide, a mixture of water-soluble polyethylene glycols as the suppository base, a mixture of an organic acid and an inorganic bicarbonate as the foaming agents and a mixture of an amphoteric surfactant and a water-soluble film-forming agent as the foam-stabilizing agent.
摘要:
This invention is concerned with producing ethylene and/or 1,2-propylene glycol by the reaction of a non-cyclic oxymethylene compound formed by the hydration or acetalization of formaldehyde with a compound containing one or more of silicon, germanium and tin bonded therein which functions as an addend in a photochemically or thermally induced radical reaction, to form a 1,2-dioxyethylene containing compound, and cleaving such 1,2-dioxyethylene containing compound to form the glycol thereof.
摘要:
Ammonium carboxylates having the general formula: ##STR1## wherein R is hydrogen or a substituted or unsubstituted hydrocarbon radical. The defined carboxylates promote the formation of alkane polyols in a homogeneous liquid phase mixture wherein hydrogen and carbon monoxide are reacted in the presence of a rhodium carbonyl complex at a temperature of from about 100.degree. C. to 375.degree. C. and a pressure of from about 500 psia to about 50,000 psia.
摘要:
This invention relates to the manufacture of such valuable chemicals as polyhydric alcohols, their ether and ester derivatives, oligomers of such alcohols and monohydric alcohols and their ether and ester derivatives by reacting hydrogen and oxides of carbon in the presence of a rhodium carbonyl complex and a trialkanolamine borate.
摘要:
This invention relates to the manufacture of ethylene glycol, methanol, and derivatives thereof from the reaction of hydrogen and carbon monoxide, by a homogeneous catalytic process using a cobalt-containing compound and an organosilicon compound having least one hydrogen bonded to silicon (--Si--H).
