A compound having a V2 receptor agonistic activity is provided. Providing a pharmaceutical composition which contains, as an active ingredient, a compound represented by general formula (I) described below: [Ris formula described below: (A is a lower alkylene group which may be substituted with lower alkyl group; Ris a hydrogen atom; Ris a hydroxyl group, an aromatic heterocyclic group which may be substituted with lower alkyl group, carbamoyl group); Ris a hydrogen atom or lower alkyl group; Ris lower alkyl group which may be substituted with 1-3 fluorine atoms, or halogen atom; Ris a five-membered aromatic monocyclic heterocyclic group, five-membered non-aromatic monocyclic heterocyclic group, (provided each heterocyclic groups contain at least one nitrogen atom and may be substituted with a lower alkyl group); and Ris a lower alkyl group, halogen atom], or pharmacologically acceptable salt thereof.

Benzoazepine derivative and medical use thereof

A polyester having a good color tone (a high L value and a low b value) and a low acetaldehyde content is obtained by using a catalyst containing a reaction product of (A) a titanium compound (1) represented by the general formula (I) and/or a titanium compound (2) obtained by reacting the titanium compound (1) of the general formula (I) with an aromatic polyhydric carboxylic acid represented by the general formula (II) or an anhydride thereof, with (B) a phosphorus compound (3) represented by the general formula (III). [wherein R, R, R, Rand R=a C-Calkyl group, k=1 to 3, m=2 to 4, and R=a substituted or non-substituted C-Caryl group or a C-Calkyl group].

Catalyst for preparation of polyester and process for preparing polyester using the catalyst

A through process comprising depolymerization reaction of used PET bottles with EG, recovering DMT by ester interchange reaction with MeOH, obtaining terephthalic acid by hydrolysis of the recovered DMT, and manufacturing a PET polymer which can be used for manufacturing PET bottles again by using the terephthalic acid.

Method for recycling pet bottle

To provide a polyester hollow molded product which eliminates the possibility of contaminating its contents, retains excellent transparency after it is used repeatedly by recycling and can be re-used with a substantially unscratched surface. The polyester hollow molded product has a polyester coating layer on the exterior surface and the coating layer can be removed with hot water or alkaline aqueous solution.

Coated hollow polyester molding, method of reclaiming the same, and solution for surface coating

An aromatic polyester composition includes 5 to 95 wt % of an ethylene naphthalenedicarboxylate copolymer and 95 to 5 wt % of an ethylene terephthalate (co)polymer, has a compatibility between these polymers of 0.15 to 0.5, and has a melting point which lowers depending on the content of ethylene naphthalenedicarboxylate. This composition has excellent compatibility, transparency, barrier properties and heat resistance and is an excellent raw material for forming various molded products, particularly bottles. A bottle and its production process are also disclosed.
