DEMONSTRATION PROCEDURE SET - EF 1

Description:

These procedures are designed to reproducibly illustrate, in a realistic and convincing way, the superiority of ALKEN EVEN-FLO® over competitive products in the market.

Equipment & Ingredients:

• A supply of aluminum weighing dishes (#3015-22 from

  Weber Scientific

  washed and dried, so as to remove any mold release coating which could interfere with a surfactant properties demonstration. Water drops applied to the weighing dish should form distinct beads. If the droplet spreads out, the dish needs further cleaning. For cleaning, first use an ammonium lauryl sulfate based dish washing detergent, such as Dawn®. Don't use a fatty soap that could leave behind a film of skin softening lotion or other oils. Avoid cleaning the aluminum with anything which contains free alkali, as the alkali may etch or otherwise oxidize the aluminum surface. If this fails to remove the coating, try a little isopropyl alcohol or acetone to clean it. If the aluminum dishes still won't make the water form a bead, high density polyethylene or polypropylene weighing dishes may be used for demonstrating the surfactant part of the test. Polystyrene should be avoided.
  
  
• 7 glass 1 oz. bottles for the following:

  Water Even-Flo® 905 or 908 K Even-Flo® 910 Even-Flo® 910E Sludge non-detergent SAE-30 or equivalent motor oil Competitor's additive

• A supply of disposable glass bottles or large culture tubes (four are needed per emulsification test cycle)
  
  
• 2 glass rods for stirring samples
  
  
• 1 small spatula for dispensing sludge from its bottle
  
  
• 7 glass droppers, with rubber bulbs, or a package of low density polyethylene disposable droppers.
  
  
• Samples of Alken Even-Flo® formulas and the competitor's additive in some of the bottles mentioned in item #3.
  
  
• A sludge sample from a petroleum or fuel tank, the consistency of peanut butter. If necessary, it may need to be cooked to reach this consistency.
  
  
• Matches or small cigarette lighter.

Emulsification Test Procedure:

Purpose: This demonstration is designed to show the presence of the highly effective surfactants in Alken Even-Flo® 905 or 910E, which will bring about emulsification and dispersion of water in the oil. Alken Even-Flo® 910 will demulsify, separating cleanly and totally from the water.

• Place 1 ounce of water in each of four small glass bottles.
• Add 5 drops of Alken Even-Flo® 905, 910E, and 910 to the first three bottles, and 5 drops of competing product in the fourth bottle.
• Shake a few times until a white emulsion forms.
• Allow all bottles to sit and observe in one hour, 24 hours and 48 hours.

Flash Point Test Procedure:

Procedure: Solvent-type products (those that form two distinct layers, as seen in the previous demonstration) will often have a flash point that is low enough to be dangerous. If the flash point (sometimes even the fire point) is at, or below room temperature, that fact can be demonstrated as follows:

• Pour a small amount of the competing product into one of the metal dishes.
• Keep another metal dish handy to smother the fire, should the product ignite, during the next step.
• Pass a lighted match slowly accross the surface, about ¼ inch above the product.
• Repeat steps 1 & 2 with Alken Even-Flo® to show that our product will not ignite.
  
  
  

Sludge Dissolving Test Procedure:

• Place a small dab of sludge in the center of two metal dishes
• Add 3 drops of water to both
• Cover the whole with a heavy non-detergent motor oil (SAE 30 or equivalent). This simulates conditions at the bottom of an oil-tank. The motor oil allows the action to be visible.
• Add 2 droppers of competitive treatment to one dish and 2 droppers of Alken Even-Flo® to the other.

• At times, it may be advantageous to hasten the action by slightly warming the dishes with a lighted match held under them Be careful using a competing product with a low flash point.
  

Surface Tension Test Procedure:

• Place a drop of water, about ¼ inch in diameter, in each of two aluminum weighing dishes.
• To one of these dishes, add a drop of the competitive product, to the other add a drop of Alken Even-Flo®. Add the products very gently by just bringing the drop of treatment into contact with the edge of the water drop.
• Most competitive products will simply surround the water drop and slightly increase its size. Alken Even-Flo® on the other hand, will reduce the surface tension of the water to such an extent that it will immediately spread over the entire surface of the dish.
