The difference of main gasoline octane boosters


To increase gasoline octane boosters, commonly refineries will add some octane boosters, like alkyl oil, MTBE, Aromatic hydrocarbon, n-methyl aniline or MMT, or upgrade refinery equipment, but it cost too much.
Many customers ask what is the difference among different octane boosters, i told them first they have to check their country regulations, because some type of octane boosters are forbidden to be used in some country, like China forbid to use any N-methylaniline or MMT in gasoline, but China has several N-methyl anline and MMT plants like us(SNF, inquiry Email:lignosale@gmail.com), and all our products are exporting abroad.
MMT, chemical name:Methylcyclopentadienyl Manganese Tricarbonyl, CAS No.: 12108-13-3, is most cost effective octane booster, with dosage 0.01%, can increase 2-3unit RON, but it is not a chemical which can keep increasing RON by continuously increasing dosage, commonly it can increase 10 RON max in naphtha oil or common pressure gasoline, and most countries control the Mn contents in exhaust, usually we recommend customers add 18mgMn/L mmt. it's working way is chemical process. when gasoline is burn in engine, MMT can decomposed to active Manganese oxide particles and break the peroxide in engine, decrease the concentration of peroxide in pre-flame reaction, and at the same time, cut part of chain reaction, so MMT can stop auto-fire, and increase antiknock properties. therefore, if u test MMT performance, u can't use simple RON reader, but need to use a motor, similar like car engine, to test it in a private room of lab, like below

 MMT antiknocking efficiency is twice as tetraethyl lead  The gasoline RON improvement effect of adding 18mg/l MMT is equivalent to the RON improvement effect of blending MTBE of 8%-10% with gasoline.
MTBE or Alkyl oil increase gasoline octane booster by their physical properties, because their own RON number is high(about 90-115), when they are mixed with gasoline ,can increase RON.
N-methylaniline with dosage 2.5%, can increase RON 4-5 unit.
pls.note both MMT and N-Methylaniline are 6.1 class dangerous chemical, and both of them should avoid direct sunshine, keep them in opaque bottle or drums, or it can be easily decomposed.

we specialized in producing gasoline octane booster MMT in China, and export our products all over the world, welcome to make inquiry by Email: lignosale@gmail.com

Part Four  First-aid measures  

  Skin contact
Flush contaminated skin with plenty of water. Continue to rinse for at least 10 minutes. Remove
contaminated clothing and shoes. Wash contaminated clothing thoroughly with water before removing
or wear gloves. Wash clothing before reuse. Clean shoes thoroughly before reuse. Get medical attention
immediately.

  Eye contact
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Check for and remove any contact lenses. Get medical attention immediately.

    Inhalation
Move exposed to fresh air. If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus. Keep person warm and at rest. If not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel. It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation. If unconscious, place in recovery position and get medical attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.Get medical attention immediately.

Ingestion
     Remove dentures if any. Move exposed person to fresh air. Keep person warm and at rest. If material has
been swallowed and the exposed person is conscious, give small quantities of water to drink. Stop if the exposed person feels sick as vomiting may be dangerous. Aspiration hazard if swallowed. Can enter lungs and cause damage. Do not induce vomiting unless directed to do so by medical personnel. If vomiting occurs, the head should be kept low so that vomit does not enter the lungs. Never give anything by mouth to an unconscious person. If unconscious, place in recovery position and get medical attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.Get medical attention immediately.



Part Five   Fire-fighting measures
Special exposure hazards
Flammable liquid and vapour. Vapour may cause flash fire. Vapours may accumulate in low or confined areas or travel a considerable distance to a source of ignition and flash back. Runoff to sewer may create fire or explosion hazard. This material is very toxic to aquatic organisms. Fire water contaminated with this material must be contained and prevented from being discharged to any waterway, sewer or drain.
Harmful combustion products
Some Irritating and corrosive toxic gas were possibly produced.
Extinguishing media Suitable
Use dry chemical, CO2, water spray (fog) or foam.Do not use water jet.
Part Six  Accidental release measures
1.Personal precautions : Immediately contact emergency personnel. Eliminate all ignition sources. Keep unnecessary personnel away. Use suitable protective equipment. Do not touch or walk through spill material.
2.Environmental precautions : Avoid dispersal of spill material and runoff and contact with soil, waterways, drains and sewers.
3.Treatment method: Rapidly evacuate workers from the contaminated area to the safe place. It is recommended that emergency personnel wear goggles and self-contained positive pressure respirators, protective clothing.  Use vacuum sucking device or clean up the material and then place it in the appropriate special container,  the overflow material should be immediately cleaned. During cleaning,  use appropriate protective facilities,  and keep ventilation.






Part Seven  Handling and storage
Handling
Avoid contact with eyes, skin and clothing. Keep container closed. Use only with adequate ventilation. Do not breathe vapour or mist. Keep away from heat, sparks and flame. To avoid fire or explosion, dissipate static electricity during transfer by earthing and bonding containers and equipment before transferring material. Use explosion-proof electrical (ventilating, lighting and material handling) equipment. Wash thoroughly after handling.
      Storage
Keep the product away from other products. The container should be stored in a cool,
well-ventilated area. Keep container closed before use. Avoid all possible sources of
ignition ( a spark or a flame ). Use the explosion-proof lighting, ventilation facilities.  
Forbidden to use the mechanical equipment and tools that are liable to produce the
spark.  Storage areas should be equipped with emergency treatment equipment for
leakage and suitable collecting  materials.keep in a dark place.
