摘要:
An amine derivative of following general formula (I) or (II) (wherein R1 represents a heteroatom-containing C¿1?-C40 hydrocarbon group which may have a ring structure, etc.; R?2 to R6¿ each represent a C¿1?-C10 hydrocarbon group, hydrogen, etc.; A?1¿ represents (i) or R?15-Z-R16(CH¿2)n-; B1 represents hydrogen, a C¿1?-C10 hydrocarbon group, nitrogen, etc.; and C?1¿ represents hydrogen, a C¿1?-C10 hydrocarbon group, nitrogen, alcohol residue, phosphoric acid residue, etc.); a dermatologic preparation containing the same; and a process for producing the amine derivative. The amine derivative has excellent effects of smoothing wrinkles and improving keratodermia.

Optisch aktive Aminoalkohole werden hergestellt, indem man optisch aktive Aminosäuren in Gegenwart von Ruthenium-Katalysatoren mit Wasserstoff reduziert.
摘要:
A tertiary aminoalcohol having a tert-amino group(s) in the main chain and hydroxyl groups at the terminals. The use of this compound for purposes different from that of ordinary amines and amine derivatives is expected. A process for producing the tertiary aminoalcohol wherein a catalyst comprising copper, a transition metal element of the fourth period and a platinum group element of the group VIII, and further optionally containing an alkali metal or an alkaline earth metal is used. A process for producing polyurethane using the above-mentioned tertiary aminoalcohol which can solve the problems occurring in the production of a polyurethane using a tertiary amine which has a strong irritating odor and is highly irritant to the skin as a catalyst, for example, deteriorations of working atmosphere and sales appeal of the polyurethane. The chemical structure of the above-described tertiary aminoalcohol is as follows:
摘要:
A process for preparing nitrogen-containing compounds which comprises contacting a carboxylated N-monosubstituted nitrogen-containing compound or a carboxylated N,N-disubstituted nitrogen-containing compound with a mixed metal oxide catalyst under conditions effective to produce the nitrogen-containing compound.
摘要:
A process for preparing the superconductive material MBa2Cu3Ox, M being, inter alia, yttrium and x being from about 6.5-7 and a precursor material MBa2Cu3Oy, y being from about 6-6.5, by controlled heating and cooling in a controlled atmosphere.
摘要:
Metal alkoxides, including those not containing ligands derived from an alkoxy alcohol, can be solubilized in an alkoxyalkanol solvent. The resulting solution is useful in the fabrication of metal oxide films on a substrate.
