If RXH is not acid enough to release a proton at alkaline pH, as it is the case with amines, then the reaction has to be carried out in two steps. During the first step the first EO mole is added at acid pH, so that the amine is transformed in ammonium. The reaction produce the mono-, di- and tri-ethanol amines.
Proton release from ammonium NH4+ → NH3 + H+ (here RX- is NH3) Then, the three condensation reactions:
NH3 + EO → NH2CH2CH2OH (mono-ethanol amine MEA)
NH2CH2CH2OH + EO → NH(CH2CH2OH)2 (di-ethanol amine DEA)
NH-(CH2CH2OH)2 + EO → N(CH2CH2OH)3 (tri-ethanol amine TEA)
With an alkyl amine, first the alkyl ammoniumion is formed and it is deprotonated:
RNH3+ → RNH2 + H+ (here RX- is RNH2)
RNH2 + EO → RNH-CH2CH2OH (mono-ethanol alkyl amine)
RNH-CH2CH2OH + EO → RN(CH2CH2OH)2 (di-ethanol alkyl amine)
Once the ethanol amine is attained, the EO polycondensation is carried out at alkaline pH as previously. In many instance the first ethoxylation is stopped when the monoethanol alkyl amine is formed in order to avoid the polycondensation in more than one chain.

On exposure to air it gradually absorbs oxygen and darkens in color and develops a more pronounced odour. It decomposes when heated at 80 to 100 °C.
An unsaturated fatty acid that is the most widely distributed and abundant fatty acid in nature. it is used commercially in the preparation of oleates and lotions, and as a pharmaceutical solvent. Major constit. of plant oils e.g. olive oil (ca. 80%), almond oil (ca. 80%) and many others, mainly as glyceride. Constit. of tall oil.
Also present in apple, melon, raspberry oil, tomato, banana, roasted peanuts, black tea, rice bran, cardamon, plum brandy, peated malt, dairy products and various animal fats. Component of citrus fruit coatings. Emulsifying agent in foods Oleic acid is a monounsaturated omega-9 fatty acid found in various animal and vegetable fats. The trans isomer of oleic acid is called elaidic acid.

Sodium Metasilicate is incompatible with acids, bronze, aluminum, brass, copper, lead, tin, zinc and other alkali sensitive metals.
Physical and Chemical Properties
Sodium metasilicates are white, free-flowing, granular products that feel slippery to the touch when wet. These products do not have a distinguishing odor. Sodium metasilicates are stable at normal temperatures and pressures and are not combustible. Spills of sodium metasilicate can be very slippery when wet.
