Provided is a foam discharger including: a mixing portion for mixing a liquid agent and a gas to foam the liquid agent; a discharge opening for discharging the foamed liquid agent; and a flow path in communication with the discharge opening, and for supplying the foamed liquid agent from the mixing portion to the discharge opening. The discharge opening is provided with a first porous member. On an upstream side of the first porous member, a cross-sectional area of the flow path on a cross section orthogonal to a supply direction in which the foamed liquid agent is to be supplied increases along the supply direction. The cross-sectional area of the flow path at the discharge opening is at least 1.2 times the minimum cross-sectional area of the flow path.

Foam discharger

A foam discharger includes a foamer mechanism (), the foamer mechanism () includes: a liquid flow path () through which liquid supplied from a liquid supply unit to a mixing part () passes; and a gas flow path () through which a gas supplied from a gas supply unit to the mixing part () passes, the liquid flow path () includes an adjacent liquid flow path () having a liquid inlet () open to the mixing part (), the gas flow path () includes a plurality of adjacent gas flow paths () each having a gas inlet () open to the mixing part (), and the liquid inlet () is arranged at a position corresponding to a merging part () of gases supplied from the plurality of adjacent gas flow paths () to the mixing part () via the gas inlet ().

A foamer mechanism () of a foam dispensing container has a gas-liquid contact chamber (), a liquid agent flow passage () through which a liquid agent supplied from a liquid agent supply portion () to the gas-liquid contact chamber () passes, and a gas flow passage () through which a gas supplied from a gas supply portion () to the gas-liquid contact chamber () passes. The gas flow passage () has a gas opening () that is open to the gas-liquid contact chamber (). The liquid agent flow passage () branches into plural branch flow passages (for example, branches into a first branch flow passage () and plural second branch flow passages ()). Each of the plural branch flow passages has a liquid agent opening () that is open to the gas-liquid contact chamber (). The liquid agent openings () are respectively arranged at positions on the both sides sandwiching an extension region () of an adjacent flow passage () which is a part of the gas flow passage () adjacent to the gas opening ().

Foam discharge container

The invention relates to a process for producing a tertiary amine, which includes reacting an alcohol with a primary or secondary amine gas in the presence of a catalyst with an agitating vessel under the stirring conditions where the ratio (P/P) of agitating power at the time of the maximum flow rate of an introducing gas (P[W]) to agitating power at the time of no introduction of the gas (P[W]) becomes 10or more wherein Nis the gas flow number, and N=Qg/ndwhereupon Q[m/s] is the flow rate of an introducing gas, n [1/s] is the number of revolutions, and d [m] is the diameter of an agitating impeller.
