CHAPTER I
PRODUCT OVERVIEW
General details
Phosphonicacidsare organicderivativesof phosphonicacid of the formR-PO3H2.
Commonlyusedwatertreatmentchemicals inIndiaare givenbelow.
The introduction of an amine group into the molecule increases the metal binding abilities of the
phosphonate.The stabilityof the metal complexesincreaseswithincreasingnumberof phosphonic acid
groups. Phosphonates are highly water soluble, non-volatile and highly sorptive chemicals.
The other phosphonate used to a much lesser extent are,
 Hexamethylene diamine tetramethylene phosphoric acid (HMDTMP)
 Ethylene diamine tetramethylene phosphoric acid (EDTMP)
The keypropertiesof Organophosphonatesare:
 Thresholdeffectandcrystal distortion.
 HydrolyticStability.
 Sequestrationcharacteristics.
 Deflocculation.
 Chlorine stability

5. 5
Use of organo phosphonates in boiler water treatment
In the operation of steam boiler, the major problems are faced due to scaling and on account of
corrosion.
In the process of making steam in a steam boiler, the steam which leaves the boiler is almost pure
water. The water remaining in the boiler becomes more concentrated with the impurities.
After reaching a certain concentration and due to the inverse solubilities of some of these impurities
they come out of solution and begin to adhere to the hot heat exchange surfaces such as the boiler
tubes. This causes loss of efficiency, corrosion and mechanical failure. As a solution to this condition,
some of the impuritiescanbe removedmechanicallybefore enteringthe boiler. In most cases a certain
percentage of the impurities are removed mechanically followed by the addition of chemicals whose
properties result in the elimination or reduction of deposits caused by the remaining impurities.
The impuritiesthatare mainconcernsina steamboilerare hardness (Ca and Mg) and iron which enters
the boiler via the make-up water as calcium and magnesium bicarbonate. These compounds are quite
soluble.
The problembeginsasheatisaddedto the boiler andmuch of the calcium becomes calcium carbonate.
Calciumcarbonate issparinglysolubleandwill precipitate. Magnesium will also form sparingly soluble
compounds such as magnesium silicate and magnesium hydroxide.
Iron enteringthe boiler as iron bicarbonate with the make-up water or as corrosion products from the
condensate,feedwaterorboileritself isespecially troublesome. Because the iron compounds formed
underboilerconditionsare soinsolubleitisimperative thattheybe dealtwith.Itis also speculated that
iron hampers the dispersing ability of polymers by deactivating their functional groups.
The two main chemical methods of dealing with hardness and iron in boilers are to intentionally
precipitate the impuritiesinsome formwhichis lesstroublesome thanthe untreatedspecies or to keep
the impuritiesinsolutionordispersedsothatprecipitationanddepositsare not formed. In fact, usually
a dynamic combination of sequestration and dispersion takes place.

6. 6
Use of organo phosphonates in cooling watertreatment
In the case of cooling water systems, biofouling is the major problem. The problems arise due to
reverse solubilityof calciumcarbonate and the instability of calcium bicarbonate. Calcium bicarbonate
breaks down to form calcium carbonate, which precipitates easily and forms scales.
Phosphonatesact asscale inhibitorsby adsorbingontospecificcrystal nuclei surfacesof insolublesalts,
thuspoisoningfurthercrystal growth.Theyusuallycontainmultiplephosphonate groups(R-PO3H2,R¼
organicchain) most commonlyfoundintheirdeprotonatedform, due tothe particularpHrange of
operation.
Organophosphonates,insubstoichiometricamountspreventorretardthe precipitationof scale forming
salts.Phosphonate interfere with the nucleation of the hardness crystal causing much higher levels of
hardnesstostay insolutionthanwouldbe possible with untreated water. The inhibitor is adsorbed on
the surface of scale forming crystals during the process of crystallization. This retards the growth of
crystalsand whentheyare formedtheyare highlydistortedpreventingorderlylattice type growth. This
changes the adherence characteristics of the scales formed leading to a soft sludge rather than an
adherent scale, which is easily dispersed by the movement of water.
Suspended particles and dirt in cooling water generally have a negative surface charge. Anionic
polymers increase this negative surface charge and keep the particles separated. Cationic dispersant
when used should be carefully controlled, since the positive charge might be expected to co2 agulate
the negatively charged particles, leading to the formation of dense particles. Addition of cationic
dispersants also involves greater expense since a higher dosage is required as the charge on the
suspended particles would neutralize before sufficient positive charge was built up to keep them
separated.
Organophosphonates exhibit good molecules stability towards chlorine, which is commonly used as a
biocide incoolingwatersystem.Incase where greatermoleculesstabilitytochlorine is desired. HEDP is
preferable to ATMP since it contains nitrogen and therefore chlorine demand for the formation of
chloramines is totally absent.

7. 7
Advantages of organophosphonates over polyphosphates
Reductionin sludge formation: Polyphosphates,whenusedascorrosioninhibitor,give rise toexcessive
orthophosphate sludgeswhereasOrganophosphonateswith zincgive good corrosionprotectionwithout
leading to any sludge formation.
Optimum usage level: Due to the sequestering ability of phosphonate, the zinc ions are present in a
complexed form limiting the rate of reaction of zinc with hydroxyl ions. Therefore, optimum
concentrationof zinc hydroxide allows the formation of a thin hydroxide film at the surface giving the
desired corrosion resistance.
Superior sequestering ability of heavy metals: The sequestering ability of phosphonate enables it to
control heavymatter(Fe,Cu& Zn) depositsandthiscontrol isfar superior to other traditional chelants.
Phosphonate also help to disperse suspended particles.Phosphonate provide excellent control of
hydrated ferric oxide deposits which are formed as a result of corrosion. They adsorb on the particle
surfaces and reduce the attractive forces between individual iron particles.
Higher stabilityand resistant to hydrolysis: Phosphonatesdonot hydrolyse easily like Polyphosphates
and are useful to avoid Calcium precipitation even in alkaline waters. The carbon to phosphorus to
oxygen(CPO) bondinginOrganophosphonatesismore resistant to hydrolysis or cleavage than the COP
bond in phosphate esters and the OP bond in polyphosphates. Organophosphonates are extremely
stable to hydrolysis as compared to polyphosphates at elevated temperature and extremes in pH for
extended periods of time.
Choice of organophosphonate:
From the two most commonly used phosphonate for cooling water treatment HEDP is preferred to
ATMP for the following reasons:
ATMP is more corrosive toCu coolingsystemsinvolving Cu or Cu alloys, are therefore very sensitive to
ATMP. WithATMP one would thenhave to use CucorrosioninhibitorslikeThiazolesandTrizoles making
the treatment more expensive.
HEDP has betterstabilitytochlorine thanthe Nitrogencontaining ATMP.Nitrogencontainingcompound
have a tendency to form chloramines. Though, when complexed with Zinc, ATMP exhibits stability
towardschlorine it should be used with caution in chlorinated cooling water systems especially when
continuous chlorination is used.
The addition of Zinc to ATMP to a certain extent inhibits the dissolution of copper. In the presence of
ATMP, however,the powerfuloxidizing potentialof chlorine promotes the dissolution of copper, when
chlorine is used as a biocide.
