Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
163 words
PROCESS WHICH COMPRISES: (1) ADMIXING A SATURATE HYDROCARBON STOCK CONTAINING METHYLCYCLOPENTANE WITH A C4 HYDROCARBON STOCK CONTAINING N-BUTENE AND ISOBUTYLENE AND WITH SULFURIC ACID HAVING A STRENGTH OF 88100%; (2) MAINTAINING THE MIXTURE AT A TEMPERATURE IN THE RANGE OF -30 TO +20*C. FOR A TIME TO EFFECT REACTION, WHEREBY METHYLCYCLOPENTANE IS CONVERTED TO DIMETHYLDECALINS, ISOBUTYLENE IS CONVERTED TO ISOBUTANE AND N-BUTENE REACTS WITH THE SURFURIC ACID TO FORM ESTERS; (3) SEPARATING FROM THE REACTION MIXTURE A HYDROCARBON PHASE CONTAINING THE DIMETHYLDECALINS AND AN ACID PHASE CONTAINING THE ESTERS; (4) SEPARATING DIMETHYLDECALINS FROM THE HYDROCARBON PHASE; (5) ADMIXING THE ACID PHASE WITH SATURATE HYDROCARBON STOCK CONTAINING AT LEAST ONE HYDROCARBON HAVING A TERTIARY CARBON ATOM; (6) MAINTAINING THE RESULTING MIXTURE AT A TEMPERATURE IN THE RANGE OF 20 TO 100*C. FOR A TIME TO EFFECT REACTION, WHEREBY ALKYLATION OF SAID SATURATE HYDROCARBON STOCK WITH THE ESTERS OCCURS; AND (7) SEPARATING FROM THE RESULTING REACTION MIXTURE AN ALKYLATION PRODUCT PHASE AND AN ACID PHASE
