摘要:
An apparatus for the continuous reaction of a liquid with a gas which comprises: two externally cooled, substantially concentric, stationary circular reaction surfaces, a rotatable circular rotor having a lid as well as a skirt extending from the upper end of the space between said reaction surfaces partway to the bottom of said space, a distribution ring for supplying recycled reaction product for quenching the reaction mixture which ring is equipped with a bedplate devised to form in combination with the lower end of a cooling jacket provided on the outer reaction surface a downwardly opening inlet for the recycled reaction mixture; means for turning the rotor and means for passing the reactant liquid and the reactant gas in parallel streams from the upper part to the space between said reaction surfaces and said rotor; and a circular wall beneath the outer reaction surface which is located concentrically with said reaction surface.

METHODS OF SEPARATING THE BY-PRODUCT SULFURIC ACID FROM THE REACTION MIXTURE RESULTING FROM PHOTO-SULFOXIDATION OF PARAFFINS IN WHICH THE CONCENTRATION OF THE SULFURIC ACID IS FROM 30 TO 95% BY WEIGHT, WHICH COMPRISE THE STEP OF NEUTRALIZING SAID REACTION MIXTURE WITH CAUSTIC ALKALI OR CONTACT THE REACTION MIXTURE WITH UNDILUTED SULFURIC ACID, THEREBY SETTLING THE BY-PRODUCT SULFURIC ACID WITHIN THE REACTION MIXTURE.
摘要:
A structure of a dispenser spout built in a carton which keeps the dispenser spout closed while not in use, wherein a means to hold securely a flap of dispensing spout capable of opening and closing freely is provided to the carton, said flap being formed by cutting a part of the carton body.

HEXAGONAL SYSTEM PRISMATIC CALCIUM SULFITE, WHICH IS USEFUL AS A FILLER FOR THERMOPLASTIC RESINS, IN PREPARED BY CONTACTIG AN SO2-CONTAINING GAS WITH A SUSPENSION OF CALCIUM HYDROXIDE, PRECIPITATED CALCIUM CARBONATE, OR MIXTURES THEREOF WHEREIN THE SO2-CONTAINING GAS IS PASSED CONTINUOUSLY THROUGH A PLURALITY OF CONTACT ZONES IN WHICH THE FIRST OF SAID ZONES HAS A TEMPERATURE OF 50*-100*C. AND A PH OF 3-6 AND EACH SUCCEEDING CONTACT ZONE HAS A TEMPERATURE OF 50*-100*C. AND A PH OF HIGHER THAN 6, WHILE SIMULTANEOUSLY PASSING THE SUSPENSION THROUGH SAID PLURALITY OF CONTACT ZONES COUNTER-CURRENTLY TO THE DIRECTION OF THE FLOW OF THE SO2-CONTAINING GAS.
摘要:
The invention relates to a novel thermoplastic resin composition of improved color and strength characteristics consisting essentially of a thermoplastic resin and (1) calcium sulfite or (2) a mixture of calcium sulfite and a calcium sulfate compound; optionally also with a minor amount of glycerine, ethylene glycol and boric acid.
摘要:
Plastic materials are disclosed, which have a foamed or laminated structure and are suitable as construction materials and furniture materials. They are very superior in the mechanical strength and difficultly combustible. Even if they catch fire, no poisonous gases are produced.
摘要:
A METHOD FOR PREPARING A POROOUS THEREMOPLASTIC RESIN SHEET COMPRISING THE PROCESSING STEPS OF: FORMING A SHEET WITH A COMPOSITION CONTAINING THERMOPLASTIC RESIN KNEADED TOGETHER WITH ACID-SOLUBLE INORGANIC PARTICLES AND THEN SOAKING THE SHEET THUS OBTAINED IN A TREATING LIQUID CONSISTING OF ACID AQUEOUS SOLUTION FOR DISSOLUTION OF SAID INORGANIC PARTICLES OUT OF SAID SHEET.
摘要:
A method for the preparation of a filler to be used with thermoplastic resins comprising a process of making the mixture of two or three members selected from the group consisting of sulfur dioxide, sulfur trioxide and carbon dioxide act on calcium hydroxide in the presence of water or a process of making either sulfur dioxide or sulfur trioxide or the mixture thereof act on calcium carbonate in the presence of water. Thermoplastic compositions containing the coprecipitated filler mixture have superior physical characteristics when compared to thermoplastic compositions which contain filler mixtures mechanically mixed.

1.. A PROCESS FOR SULFONATING LIQUID SULFONATABLE ORGANIC MATERIAL SELECTED FROM THE GROUP CONSISTING OF ALKYLARYL HYDROCARBONS, OLEFIN HYDROCARBONS, ALIPHATIC ALCOHOLS AND ETHOXYLATES THEREOF AND ALKYL PHENOLS AND ETHOXYLATES THEREOF, IN WHICH A CONTINUOUS THIN FILM OF SAID LIQUID SULFONATABLE ORGANIC MATERIAL IS FLOWED ALONG AN EXTERNALLY COOLED REACTION SURFACE IN A REACTION ZONE AND IS CONTACTED IN SAID REACTION ZONE WITH A SEPARATELY SUPPLIED FIRST STREAM OF A MIXTURE OF GASEOUS SULFUR TRIOXIDE AND INERT GAS FLOWING IN PARALLEL WITH SAID FILM TO EFFECT SULFONATION OF SAID MATERIAL, WHREIN THE IMPROVEMENT COMPRISES: CONTINUOUSLY FLOWING A SEPARATELY SUPPLIED SECOND GASEOUS STREAM CONSISTING ESSENTIALLY OF AIR OR INERT GAS FREE OF SO3 INTO THE FEED END OF SAID REACTION ZONE IN PARALLEL WITH, IN CONTACT WITH AND BETWEEN SAID FILM AND SAID FIRST STREAM SO AS TO FORM A PARALLEL FLOWING LAYER OF SAID SECOND GASEOUS STREAM BETWEEN SAID FILM AND SAID FIRST STREAM IN SAID REACTION ZONE, SAID SECOND STREAM BEING AT A TEMPERATURE OF FROM 10 TO 40* C. AND HAVING A FLOW RATE OF FROM ABOUR 2 TO 12 TIMES THE FLOW RATE OF SAID FIRST STREAM, THE LINEAR VELOCITY OF SAID SECOND STREAM BEING SUBSTANTIALLY THE SAME AS THAT OF SAID FIRST STREAM AND IN THE RANGE OF FROM ABOUT 20 TO 100 M./SEC/. WHEREBY TO RETARD THE INITIAL STAGE OF THE SULFONATION REACTION AND TO EFFECT THE REACTION UNDER SUBSTANTIALLY ISOTHERMAL CONDITIONS THROUGHOUT THE REACTION ZONE.
