Definitions

  • the present invention relates to a process for producing a detergent.
  • the present inventor has succeeded in the high-speed formulation of detergents with far less energy than that required conventionally.
  • the present invention provides a process for producing a detergent which comprises the step of preparing a mixture of soda ash as the main component, and a nonionic surfactant or a surfactant composition comprising an anionic surfactant and at least 40% of a nonionic surfactant, in a generally cylindrical reaction vessel, the bottom of which is provided with a substantially horizontally agitating blade turning on a substantially vertical axis, the side wall of which is provided with crosswheels turning on a substantially horizontal axis, and the upper part of which is of generally circular conical form having a curvature of 5 to 30°; and the step of reacting the mixture with vigorous agitation by means of the blade and the crosswheeis which rotate at different speeds.
  • the components forming a detergent of the present invention comprise soda ash as a builder, and a nonionic surfactant or a mixed surfactant consisting of nonionic and anionic surfactants, the soda ash amounting conveniently to 50% or more, preferably from 70 to 85% of the whole detergent.
  • the detergent of the invention exhibits a washing effect higher than that of conventional detergents. Tables 1 and 2, below, illustrate clearly how unique such a composition is, compared with conventional synthetic detergents.
  • the soda ash used as the builder in the present invention has a detergency in aqueous solution which approximates, in electrical action, to that of salts such as alkylbenzene sulfonates, linear alkylbenzene sulfonates, and sulfates of coconut oil alcohol.
  • nonionic surfactants are superior to anionic ones in permeability, solubility, etc.
  • the present invention aims at reducing the amount of surfactant used as well as attaining a synergistic detergency effect by the use of soda ash and the nonionic surfactant, by means of employing nonionic surfactant or substituting soda ash for a part of the anionic surfactant.
  • Soda ash reacts with the moisture contained in the active component by hydrolysis, and the exothermic reaction on hydrolysis (which amounts to approximately 80°C) promotes drying of the reaction product and has the effect of preventing a fall in pH caused by oxidation of oils.
  • additives such as thickeners, enzymes, sequestering agents and the like may be added as desired.
  • the accompanying drawing illustrates the apparatus wherein the process of the present invention may be carried out.
  • It is a cylindrical reaction vessel 1, approximately 1/3 of the upper part of which forms a circular cone with a curvature of 5 to 30°, and the inricr part is equipped at the vertical axis 2 at the center of the bottom with a horizontally agitating blade 3 rotating on said axis; and the side wall is provided at the horizontal axis 4 with a plurality of crosswheels (choppers) 5 fixed perpendicularly to the said axis, and rotating on the axis.
  • choppers crosswheels
  • the blade 3 is a plurality of flat blades having faces with 5 to 45° elevation angles, the peripheral speed of which is approximately 0.6 to 6.0 m.
  • the crude particles are thereby ground by the rotation of the blade, and at the same time, the crude particles themselves make a kind of spiral movement in a radical manner and upperwards by the centrifugal force and rotary component force, since the blade face forms an elevation angle.
  • the crosswheels (chopper) mounted on the horizontal axis interfers with the scattering of the particles to complete the mixing, and at the same time, grinds clods and the second cohesion (blocking) of the builder, and in addition, regulate the particles to make them round by the contacting phase in obtuse angle, to obtain the detergent in a highly dried state.
  • the process of the present invention since drying is effected in the reaction vessel with the heat of hydrolysis of the soda ash and the heat caused by the mutual friction of the particles, the energy consumption which has hitherto been regarded as inevitable for producing synthetic detergents is greatly reduced and detergency may be improved by the synergistic effect of soda ash as the main component and the nonionic portion.
  • it enables the manufacture of powdered detergents from natural vegetable oils as the starting materials, which have previously exhibited problems in profitability due to its difficulty in drying.
  • reaction bath capacity : 25 liter blade : 1, elevation angle : 30°, rotation : 150 rpm crosswheels : 3, rotation : 1500 rpm Period from preparing the product to taking out : 6 minutes.
