The anhydride is maleic anhydride and the acid is sulfuric acid. The amino alcohols are monoethanolamine, diethanolamine, triethanolamine and mono-isopropylamine.
Description
~5~Llo PE:STICTD~ sT~ R~-R~TRNn~
~ he pre6ent invention relates to a pesticide product and more particularly to a sticker-extender for postlcide sprays.
9ticker-extenders for pesticide 6prays have been known for a number oi years and are used to extend the activities oi pesticide sprays 6uch as fungicidos, herbicides and insecticides. A sticker-extender is intended to improve the performance of such pestlcides by assisting to evenly epread the pesticide and form an elastic film to keep it in place. It has been found that existing pesticide spray additives sometimes do not extend the activity of the pesticide sprays for a very long period and sometimes do not help to spread the pesticides evenly over the entire plant or do not form a suit~ble elastlc film to keep the peeticides in place. It also sometimes occurs that losses occur from rain, overhead irrigation and heavy dew and that losses also occur due to sunlight and evaporation.
:
21~60~11 Some existing sticker-extenders have poor canopy penetration and do not deposit the spray solutions deep lnto the crop foliage and others do not easily disperse in water to form emulslons.
It has been found that some sticker-extenders are more prone to flre Qnd explosion and may be dangerous to use and store.
Q~çg~
The present invention is an improvement over exlsting pesticide spray additives and has for one of its ob,~ects the provision of an improved sticker-extender for extending the activity of pesticide sprays, such as insecticides, fungicid~s and herbicides.

The stlcker-extender of the present lnventlon i8 manufactured in a two stage process. The first stage produces an lntermediate product herelnafter referred to as "lntermedlate`'. The 6econd and flnal stage produces the fLnal product hereinafter referred to as "Flnal Product".
The lntermediate preferably contains an anhydride made from an di~ase acid, such as maleic anhydride, a strong acld such as sulfuric acld and turpentlne preferably acintene P-AC turpentine. Preferably, the turpentlne amounts to almo~t twlce as much as the anhydride with the acld belng in v~ry small amounts.

In order to make the final product, the Intermedlate is added to a plurality of a number of alcohols 6uch as an isomeric alcohol and a number of amino alcoholæ. Prefer~bly, al~out 60% of the Final Product comprises lntermediate and the remalnder compr~ses the said variety of alcohols.

., ' The Intermediate 18 preferably manuf~ctured by placlng maleic anhydride into a reactor and heating it to about 170C. After the maleic anhydride is melted, it i8 agitated in an,agitator. Sulfuric acid is added to the agitator and cooling water is applied thereto.
The turpentine is then added 610wly over a two hour period.
Temperature in the agitator i8 maintained between 170-185C
and any condensatio~ may be returned by a condenser back to the reactor. PreierabIy, the temperature is. kept above 167 to prevent turpentine buildup which may result in , uncontrolled exothermic reaction. After all the turpentine has been added, the mixture is held at about 180-185C
for about two hours. The mixture is then cooled to about 40C .
Following the above procedure, a batch of Intermediate was prepared. The kettle and all piping a6sociated with the process are thoroughly cleaned. Cleaning was accomplished ....

About 9080 lb6. (1268 gallons) of the turpentine i8 applied to the kettle at about 6 gpm ~gallons per minute).
Cold water is used to maintain the temperature at about 1705 to 180C. Preferably, the temperature should not go below 165C because the reaction may stop and unreacted raw materials may build up in the system causing runaway reaction when the kettle ls heateù bac~ up to the reaction temperature. Ii the temperature falls below. 11;5C, the addition ci Turpentine should be stopped and heat should be applied to the kettle to raise the temperature up to 170 and 180 before the Turpentine addi~ion is resumed.

Once all the Turpentine is added, the reaction 8hould be held at about 170 to 180 for about 2 hour8.
Thereafter, the batch i8 cooled to about 40C. If lt i8 determined that addltlonal cook tlme is needed, the batch may be reheated to about 170 to 180C and held at tbat temperature for an additlonal 2 hour8 and thereafter allowed to cool to about 40C~
The resulting Intermedlate should have an amber color and the appearance Of a homOgeneOU8 flUid.
In general, the Final Product i8 manufactured by placing the Intermediate into an agitator and 8tarting the agitation. The Butanol, MEA, DEA and TEA are added preferably in that 8equence while maintainlng the temperature between 45C and 60C. The ~Lono-Isopropyl Amine 18 then added preferably below the 8urface of the batch while the temperatUre i8 still below 60C. The batch i8 mixed for about one hour and the Final Product should have the appearanCe Of amb~r liquld wlth a p~l Of 7.0 :~ 0.5.
The Intermediate was added to the agitator and agitation of the batch i8 8tarte About 51~2 Ib8.
- 21~o4o (769 gallons) of Butanol i5 added to the batch. The agltator i8 heated to about ~0C. About 1576 lbs. of UEA 18 added to the batch. When the temperature reaches 50C, the mixture may be cooled in any well known manner (such as through an oll recycle cooling system) and the MEA 18 contlnued to be added at a rate to hold the temperature below 60C.
Thereafter, about 464 lbs.of DEA is added and the temperature ls kept below 60C by adjusting the rate at whlch the DEA
is added. About 1367 lbs. of t~le TEA is then added and the temperature ls kept below 60'C by agaln adjusting the rate at whlch the TEA is added. About 570 lbs. of ~lono lsopropylamine is added to the batch and agaln the temperature is kept below 60 C. by ad,~ustlng the rate at which it 18 added.

22. A method of making a sticker-extender for pesticides as set forth in claim 21 wherein said first mixture comprising maleic anhydride, sulfuric acid and turpentine and said second mixture comprising a butanol, MEA, DEA, TEA and Mono Isopropylamine.
23. A method as claimed in claim 22 wherein said maleic anhydride is melted before the acid is added to it.
24. A method of making a sticker-extender as set forth in claim 23 wherein said first mixture comprises more than 50% of the total mixture.
25. A method as claimed in claim 24 wherein the butanol, MEA, DEA and TEA are added to the first mixture in that order.
23. A method as claimed in claim 25 wherein thereafter the Mono Isopropylamine is added.
27. A method as claimed in claim 26 wherein the turpentine is added slowly for a period of about two hours .
28. A method as claimed in claim 27 wherein the temperature of the mixture is maintained between 170-185°C.
29. A method as claimed in claim 28 wherein the first mixture is held at about 180-185°C for about two hours after the turpentine is added.
30. A method as claimed in claim 29 wherein the said first mixture is cooled to about 40°C.
31. A method as claimed in claim 30 wherein the temperature of the two mixtures is maintained below 60°C during mixing.
32. A method as claimed in claim 31 wherein the two mixtures is mixed for about one hour.
