Definitions

  • Another object of my invention is an apparatus which substantially is very useful as a kind of combination of a beaker-glass and a separating funnel.
  • Another object of my invention is a handy apparatus for analyzing oils, fats, soaps and the like substances.
  • My apparatus substantially consists of a bottleshaped ves el having a funnel shaped upper part with a tubular and, if desired. graduated neck provided with a cock having preferably at least two ways, said bottle-shaped vessel having further at least one preferably upwardly directed and tubulated opening in its sidewall in which fits a closing means which may be a ground stopper, if desired. provided with a tube running through it and extending into the bottle-shaped vessel and having a closing means, preferably a cock, outside said vessel.
  • the bottom of the bottle-shaped vessel may be fiat or nearly fiat; in case that the apparatus has to be used under pressure, however, I prefer a round, at least a convex bottom.
  • the neck of the apparatus may be graduated or it may be provided with a graduated and, if desired, removable elongation outside the vessel.
  • FIG. 1 represents in a somewhat schematic manner a simple glass apparatus having a flat bottom and one opening in its sidewall
  • Fig. 2 represents in the same manner a somewhat more complicated glass apparatus having a round bottom, a graduated neck and two openings in its sidewall.
  • ground stoppers ground cocks, etc.
  • I may be constructed with the aid of usual laboratory utensils, e. g. rubber stoppers, rubber tubing with pinch cocks or tubing clamps etc.
  • the bottle-shaped vessel I having e. g. a volume of 250-300 cm is provided with a fiat bottom 2 and its funnel-shaped upper part 3 terminates in a relatively narrow neck 4, having e. g. a diameter of --5 mm.
  • This neck 4 can be closed by means of a one-way stop cock 5 so that for instance it is possible to bring the interior of the vessel I in communication with the atmospherical air or with another apparatus to which it is connected at 5.
  • the vessel I In its sidewall the vessel I has a horizontal tubulated opening I which is closed by a ground stopper 8.
  • the apparatus according to Fig. 2 has a round bottom 2, a similar funnel-shaped part 3 and a graduated neck 1% which is, however, provided with a two-way stop cock 5'.
  • a two-way stop cock 5' In its sidewall are provided two tubulated openings I I and I2, which are directed upwardly.
  • the opening II can be tube 9 is bent to and ends near the bottom of the vessel I in the interior of said vessel; for some purposes, however, it is preferable to use a tube 9 which is bent upwardly.
  • a liquid or a gas e. g. an indifferent gas in case the substance to be treated is decomposed or changed by the action of air, can be introduced.
  • a gas e. g. an indifferent gas in case the substance to be treated is decomposed or changed by the action of air.
  • gas it is also possible to introduce gas into the apparatus according to Fig. 1 when the stopper 8 is replaced by a ground stopper with a tube like the stopper i l of Fig. 2, or by replacing it by a rubber stopper through which runs a tube.
  • the apparatus is first weighed in empty condition, whereupon the soap is introduced through the opening in the sidewall and the opening is closed withthe stopper. Thereupon the apparatus is weighed again in order to determine the weight of the soap.
  • the soap is thereupon decomposed in the ordinary manner with the acid and after termination of this reaction the cock is closed and the apparatus is turned upside down.
  • the watery solution is drawn off through the cock 5 in the same manner as by using a separating funnel and the fatty acids are washed with water and, if desired, dried in the apparatus. By reading their volume on the calibrated neck or by weighing their quantity can be determined. If it is desired to use the wax cake method, after decantation all water and moisture are eliminated and the apparatus is weighed a third time.
  • the drying may be carried out by passing a heated indifferent gas through the apparatus whereby the use of alcohol becomes superfluous.
  • ether extraction method the analysis is carried out much more rapidly than in the known manner and with a surprising exactness, since all the operations, including the evaporation of the ether are carried out in the same apparatus which can be Weighed exactly. spilling of fatty acids and ether is entirely excluded and the results of the determination show no errors due to sticking of the fatty acids to a number of utensils used, e. g. beakers, separating funnels, etc.
  • the neck of my apparatus with a removable and, if desired, graduated tubular elongation above the cock 5.
  • the quantity of the liquid or. solid fatty acids can be determined in. this elongation by the volumetric method or by weighing.
  • a heatable-separatory funnel which consists of a bottle having a gradually sloping upper portion uniting into a central tubular. outlet, said outlet extending a shortdistance upwardly and having a ground glass 2-way stopcock therein,
  • a heatable separatory funnel which consists of a bottle having a gradually sloping upper por tion uniting into a central tubular outlet, said outlet extending a short distance upwardly and having a ground glass 2-way stopcock therein, one passage of which is operable to open the passage through said tubular outlet when arranged to coincide therewith and another passage of which is operable to open a passage from said bottle through said stopper to the outside air when said first passage is not in the open position, and having a ground glass opening in the side wall thereof, a stopper closing said opening in said sidewall, a conduit extending through said stopper leading to the bottom portion of said bottle and a stopcock on said conduit lo cated adjacent to said stopper outside of the bottle.
  • a heatable separatory funnel comprising a bottle having a gradually sloping upper portion uniting into a central tubular outlet extending upwardly, a transversely extending ground glass stopcock in said outlet, said bottle having a ground glass opening in the wall thereof, a glass stopper located in said opening, a conduit extending through said stopper leading to the bottom portion of said bottle and a stopcock on said conduit located adjacent to said stopper outside of the bottle so that when in upright position said funnel may be heated to carry out a chemical reaction and when inverted may be used as a separatory funnel.
