Definitions

  • the subject matters of the invention are the method of producing non-phosphate detergent based on powdered sodium sesquicarbonate (Na 2 CO 3 * NaHCO 3* 2H 2 O) without additional heating and composition of detergent based on sodium sesquicarbonate.
  • the aim of the invention is to provide with new, safe, energy-saving method of producing non-phosphate powdered detergent based on sodium sesquicarbonate (Na 2 CO 3 * NaHCO 3* 2H 2 O) without additional heating and composition of detergent based on sodium sesquicarbonate
  • the subject matter of the invention is the method of production non-phosphate detergent based on sodium sesquicarbonate (Na 2 CO 3 * NaHCO 3* 2H 2 O) without additional heating which is produced in multistage process is characterised by that, the first stage (step I) consists of mixing dry compounds: sodium carbonate and bicarbonate used in weight proportion from 1,5-2,5 to 1-1, next to the above mixture is added 50% water solution of sodium sesquicarbonate in amount 15 % (counted to the whole mixture).
  • step II The whole mixture is stirred in the rotational mixer using 40 rotations /minute until the temperature reaches 45-55 C., when steam, which was produced in the exothermic reaction, crystallises the crystals of sodium sesquicarbonate from soda crystals, next the mixture is left until it reaches the ambient temperature (step II).
  • the second step is consisted of two processes: first where the temperature is reduced to the ambient temperature, and the second process where the temperature is decreased at about 7-12 C below the ambient temperature, next the temperature is rising until it reaches the ambient temperature, when is observed at this step of the process up to 90% of crystals of sodium sesquicarbonate are created.
  • step III consists of mechanical rubbing of the mixture and the surface active-agents are added.
  • the agents are such as: ethoxylate alcohol C13 of 7 moles ethylene oxide (2-5% by weight) ethoxylate alcohol C13 of 10 moles of ethylene oxide (1,5-3,0%) coconut diethanolamide (0,5-5,0 %) carboxymethylcellulose (0,5- 5,0%) optical whitening agent up to 0,3 %, in order to activate the mixture and to provide full cristallisation of sodium sesquicarbonate, the step is performed in the machine which has the rubbing screen with sieves ⁇ 2-2,5 mm, and the powdered product is mantained in the reactor where its temperature rises 5-10C up the ambient temperature, than when its temperature is stable, the active oxygen, in amount 10-20%, is added to the final product.
  • the second subject of the invention is a composition of detergent based on sodium sesquicarbonate is , characterised by consisting of: sodium sesquicarbonate 50-95 %, surface - active agents preferably ethoxylate alcohol C 13 of 3 moles ethylene oxide (2-5% by weight), ethoxylate alcohol C 13 of 7 moles of ethylene oxide (3,0-5.5%), ethoxylate alcohol C 13 of 10 moles of ethylene oxide (1,5-3,0%) coconut diethanolamide (0,5-5,0%), carboxymethylcellulose (0,5- 5,0%) optical whitening agent to 0,3%, and active oxygen, preferably sodium percarbonate in amount 10-20%.
  • surface - active agents preferably ethoxylate alcohol C 13 of 3 moles ethylene oxide (2-5% by weight), ethoxylate alcohol C 13 of 7 moles of ethylene oxide (3,0-5.5%), ethoxylate alcohol C 13 of 10 moles of ethylene oxide (1,5-3,0%) coconut diethanolamide (0,5-5,0%), carboxymethylcellulose (0,5-
  • the invention is not required any additive heating.
  • the process of manufacturing sodium sesquicarbonate is provided in ambient temperature and under normal pressure, where the heating of the substrats (while reaction is provided et the begining) uses the natural heat from the exothermic reaction.
  • Basic compounds for producing detergent based on powdered sodium sesquicarbonate (Na 2 CO 3 * NaHCO 3* 2H 2 O) according to the invention are: sodium carbonate, sodium bicarbonate known components of detergents and water.
  • the technological process according to the invention provides the method of growing sodium sesquicarbonate hydrates without using additional heating.
  • the process of crystallisation of sodium sesquicarbonate could be compared with the natural process passes in lakes.
  • the process of production of sodium sesquicarbonate does not deliver any harmful side products.
  • the process according to the invention requires little amount of water and air.
  • the whole process is easy to perform as there are natural substances used for production, the process is friendly for humans and for the environment.
  • sodium sesquicarbonate in the compounds according to the invention reduces or deletes dangerous factors for human and the environment such as: phosphates, zeolites, surface - active agents, copolimers, sulphates, silicates, disinfection agents etc.
  • the method of production non-phosphate detergent based on powdered sodium sesquicarbonate (Na 2 CO 3 * NaHCO 3* 2H 2 O) consists of many steps.
  • the first step (step I) consists of mixing dry compounds: sodium carbonate and bicarbonate which are used in weight proportion from 1,5-2,5 to 1-1, next to the above mixture is added 50% water solution of bicarbonate in weight proportion 15% ( counted to the whole mixture). The whole mixture is stirred in the rotational mixer which has 40 rotations /minute until the temperature reaches 45-55 C.
  • the photo nr. 1 from the electron microscope (500X enlarged) shows the structure which is achieved in this step. Temperature 45-55 C shows the beginning of the exothermic reaction which passes spontaneously in the process.
  • stepII the mixture is left until it reaches the ambient temperature.
  • the second step is consisted of two processes: first where the temperature is reduced to the ambient temperature (which shows fig 2), and the second process where the temperature is decreased at about 7-12 C below the ambient temperature, next the temperature is rising until it reaches the ambient temperature. At this step of the process up to 90% of crystals of sodium sesquicarbonate are created (it is shown in fig 3 and 4).
  • step III consists of mechanical rubbing of the mixture and the surface active-agents are added, the agents are such as: ethoxylate alcohol C13 of 7 moles ethylene oxide (2-5 % by weight) ethoxylate alcohol C13 of 10 moles of ethylene oxide (1,5-3,0%) coconut diethanolamide (0,5-5,0 %) carboxymethylcellulose (0,5- 5,0%) optical whitening agent up to 0,3%.
  • the step is performed in the machine which has the rubbing screen with sieves ⁇ 2-2,5 mm.
  • the powdered product is mantained in the reactor where its temperature rises 5-10C up the ambient temperature.
  • the powder is a final product when its temperature is stable.
