Title: Production of allylamine having high purity
Inventor: MORI YOSHIHIDE
IPC: C07C209/86
Filed: 1988-03-28
Abstract: PURPOSE:To easily obtain allylamine in high purity and yield, by adding a mineral acid to an allylamine solution having low allyl alcohol content to convert the amine into a mineral acid salt, distilling off allyl alcohol and isolating allylamine with an alkali. CONSTITUTION:An allylamine solution containing allyl alcohol and obtained as at least a part of a reaction liquid produced by the reaction of allyl chloride with ammonia water is added with a mineral acid such as sulfuric acid or hydrochloric acid and, as necessary, with water to adjust the pH of the system to about 2-5 and form an aqueous solution of an allylamine mineral acid salt having a concentration of 0-30%. After removing the impurities such as allyl alcohol by distillation, the pH of the system is adjusted to about 12-14 with an alkali such as sodium hydroxide or potassium hydroxide to isolate the allylamine. The separated aqueous solution of allylamine is used as it is or preferably distilled under normal pressure to recover allylamine, or is recovered to an oil-water separation step, etc., to obtain the objective compound having a purity of as high as >=99% and useful as agricultural chemicals, modifiers for polymeric compounds, etc.

Title: Extrusion molding method for foaming resin
Inventor: HORIUCHI SHOZO
IPC: B29C31/00
Filed: 1992-02-27
Abstract: PURPOSE:To stir resin and improve the mixing of a foaming material and resin by extending an injection path, protruding the same to the inside of a cylinder and injecting the foaming material from a protruded section into molten synthetic resin. CONSTITUTION:A foaming material injection path 3 passing through a cylinder wall from outside toward inside is formed in the middle of a screw cylinder 1, from which the injected foaming material and synthetic resin in the cylinder are mixed together. The foaming material injection path 3 is opened at the end of a protruded section 3a extending further to the inner side of the cylinder 1. Synthetic resin coming from the protruded section 3 and melted by the rotation of a screw 2 is pressed to the inner face of the cylinder 1 which is not smooth enough for the resin to slide while being sliding on a pressing face of a slidable screw flight 2a, and moved forward toward the downstream without rotating jointly. The protruded section 3a for injection stirs the resin, into which the foaming material is injected and mixed well.

CONSTITUTION:When a flowing passage of cooling fluid which is separated with a vacant place in a vessel 1 is composed and cooling fluid is pressed into a cooling fluid reservoir which communicate to an introducing pipe 8, this cooling fluid is pressed into the introducing pipe 8 through an inner vacant space of the end part of a revolving axis 5, and enters to a half vacant space 10, gushing out from many open holes along whole length of said introduction pipe 8, and enters in a half vacant space 11 flowing in each blade piece 6a, 6b, and flows in an exhaust pipe 9, and is exhausted to another cooling fluid reservoir through an inner vacant space of another end part of the revolving axis 5. Heat exchange is carried out on the way between working fluid of high temperature gaseous phase, which contacts from outside and inside of the wall surface of each blade piece 6a, 6b, and cooling fluid, and gaseous working fluid is condensed to the fluid phase and flows out from an outlet 3. Since each blade piece is revolving at adequate speed, working fluid of condensed fluid phase is scattered to the surroundings by centrifugal force, and the condensing heat transmission factor will become especially large.

During heat dissipation, the heat is transferred from the heat accumulating material 6 to a pipeline 3 for cooling through the porous metal 4. The porous substance having low heat resistance and wide surface area is utilized in common as heat transfer fins upon both of accumulating heat and dissipating heat; therefore, good heat transfer performance may be obtained uniformly substantially. Further, a vessel 1 is prominent in heat insulating property; therefore, the useless dissipation of accumulated heat may be restrained. According to this constitution, the miniaturized and inexpensive heat accumulating type heat exchanger can be obtained.
