FMEE Fatty Methyl Ester Ethoxylates CAS 65218-33-7 |

FMEE (Fatty Methyl Ester Ethoxylates) is a non-ionic low foamed surface active agent. Under low temperatures (below 60 degrees), it has excellent net cleaning performance. Two types are available: P816 & 24-09.

FMEE Fatty Methyl Ester Ethoxylates is a molecular formula that has Ester, which is similar to wax and oil structure. Oil, mineral oils, and paraffin wand have strong removal and dissolution ability, based on the principle of phase similar dissolution. The cloud point of this product is between 98 to 103 degrees, which allows it to be used in high-temperature processes. It has a liquid point of -5°C and is still fluid at this temperature, which makes it superior to the AEO and TX Series. FMEE, when near zero, is no longer clear and is cloudy. It still has good flow. FMEE Fatty Ester Ethoxylates had a significantly higher infiltration rate than AEO-9 and AEO-7. As a test solution, 5g/L was used. The settling time on standard canvas was then used to represent infiltration.

Three different production routes exist for FMEE Fat Methyl Ester Ethoxylates.
First, fatty acid is ethoxylated in order to get polyoxyethylene ether. Next, methanol is esterified to get. The second step is methanol polyether ethoxylation, followed by esterification with fatty acids. Two-step processes, high cost and low content of active material, polyethylene glycol or diesters are the by-products of these two routes. The third process involves the addition of fatty acids methyl ester to ethylene oxide. The process is simple and low-cost. This synthesis is used by the FMEE production companies, like Sihe Petroleum or Malepine Petroleum.

Application FMEE FMEE:
FMEE Fatty Methyl Ester Ethoxylates are used in secondary oil flooding on the oilfield. Flotation is a beneficiation process that can be applied in mining. FMEE can clean, metal degreasing and degreasing. In the textile printing and dyeing industries, it can be used to remove oil and wax. It is also used for cleaning household products and daily cleaning.
