Abstract

The present invention is directed to compounds represented by the formula (I): wherein R 1 comprises a hydrogen atom or an alkyl group having 1 to 2 carbon atoms, wherein R 2 comprises an alkylene group, an arylene group, or a heterocyclic group. The three R 2 groups may be the same or different, wherein A comprises an alkyl, an aryl, or an alkylaryl group. The three A groups may be the same or different.

Claims (33)

1 . A compound represented by formula I:

wherein R 1 is a hydrogen atom or an alkyl group having 1 to 2 carbon atoms;

wherein R 2 is an alkylene group, an arylene group, or a heterocyclic group, wherein the three R 2 groups may be the same or different; and

wherein A is an alkyl, an aryl, or an alkylaryl group, wherein the three A groups may be the same or different.

2 . The compound of claim 1 , wherein R 1 is a hydrogen atom; wherein R 2 is an alkylene group having from 1 to 5 carbon atoms; and wherein A is an alkyl, aryl or alkylaryl group having from 1 to 12 carbon atoms.

3 . The compound of claim 1 , wherein R 1 is a hydrogen atom; wherein R 2 is an alkylene group having from 2 to 4 carbon atoms; and wherein A is an alkyl, aryl or alkylaryl group having from 1 to 8 carbon atoms.

4 . S,S′,S″-((1,3,5-triazinane-1,3,5-triyl)tris(propane-3,1-diyl)) tris(4-methylbenzenesulfonothioate).

5 . S,S′,S″-((1,3,5-triazinane-1,3,5-triyl)tris(propane-3,1-diyl)) tribenzenesulfonothioate.

6 . S,S′,S″-((1,3,5-triazinane-1,3,5-triyl)tris(propane-3,1-diyl)) trimethanesulfonothioate.

7 . A method of making the compound of claim 1 , comprising:

reacting a sulfide salt having formula II:

SM 2 ,

wherein each M is independently an alkali metal cation, a proton cation, an ammonium cation, or an alkyl ammonium cation,

with an alkylarenesulfonyl halide having formula III:

wherein A is an alkylarene group and X is a halogen atom,

to form an alkylarenethiosulfonate salt having formula IV:

reacting the alkylarenethiosulfonate salt having formula IV with a haloalkylamine hydrohalide having formula V:

wherein R 2 is an alkylene group, an arylene group, or a heterocyclic group; and X is a halogen atom,

to obtain an S-(aminoalkyl) alkylarenethiosulfonate hydrohalide having formula VI:

deprotonating the S-(aminoalkyl) alkylarenethiosulfonate hydrohalide to obtain an S-(aminoalkyl) alkylarenethiosulfonate having formula VII:

reacting the S-(aminoalkyl) alkylarenethiosulfonate having formula VII with an aldehyde having formula VIII:

wherein R 1 is a hydrogen atom or an alkyl group having 1 to 2 carbon atoms,

to obtain the compound of claim 1 .

8 . The method of claim 7 , wherein the sulfide salt is sodium sulfide, the alkylarenesulfonyl halide is para-toluenesulfonyl chloride, the haloalkylamine hydrohalide is 3-chloropropylamine hydrochloride, and the aldehyde is formaldehyde.

9 . A stabilizer composition comprising the compound of claim 1 and optionally a carrier for said compound.

10 . A vulcanizable elastomeric formulation comprising an elastomer and the compound of claim 1 .

11 . The formulation of claim 10 wherein said the compound is present in an amount of from 0.01 to 30 parts per 100 parts of elastomer.

12 . The formulation of claim 11 wherein said the compound is present in an amount of from 0.1 to 5.0 parts per 100 parts of elastomer.

13 . A vulcanized elastomeric article formed from the vulcanizable elastomeric formulation of claim 10 .

14 . The vulcanized elastomeric article of claim 13 wherein said vulcanized elastomeric article is a component of a vehicle tire.

15 . The vulcanized elastomeric article of claim 14 wherein said component is a sidewall.

16 . A combustible fuel composition comprising a combustible fuel and the compound of claim 1 .

17 . A fuel additive composition comprising a fuel additive and the compound of claim 1 .
