Abstract: There are provided a method for analyzing an aqueous ammonium carbamate solution whereby the composition of an unreacted-gas absorber outlet liquid can be specified in real time, and a method for operating an unreacted gas absorber by use of the same.

Abstract: Disclosed are: a polyorganosiloxane composition which can be cured into a product having high strength and has little influence on the environment; and a cured product of the polyorganosiloxane composition. Specifically disclosed are: a polyorganosiloxane composition comprising (A) a polyorganosiloxane in which at least one end in the molecule is modified with a silanol, (B) a titanium alkoxide in an amount of 0.01 to 2 moles relative to 1 mole of the polyorganosiloxane, and (C) an ?-hydroxycarbonyl compound or a hydroxycarboxylic acid ester in an amount of 0.01 to 2 moles relative to 1 mole of the polyorganosiloxane; and a cured product of the polyorganosiloxane composition.

Abstract: Disclosed is an organosiloxane composition which can be produced at low cost and is usable for bonding of glasses, metals and resins. The organosiloxane composition can provide a cured product exhibiting excellent heat resistance and cold resistance, while having high strength and high transparency. Specifically disclosed is a polyorganosiloxane composition containing (A) a polyorganosiloxane wherein at least one end of each molecule is modified with a silanol group, and (B) 0.5-4.0 moles of a metal alkoxide per 1 mole of the polyorganosiloxane, wherein the mean molecular weight (Mw) of the polyorganosiloxane according to the mass fraction is not more than 1,000. Also specifically disclosed are a cured product of the composition and a method for producing the composition.
