Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
101 words
A PROCESS FOR SEPARATING ORGANOMETALS FROM 1-OLEFINS WHICH COMPRISES CONTACTING AN ORGANOMETAL HAVING THE FORMULA RNM, WHERE R IS AN ALKYL RADICAL CONTAINING FROM 2 TO 6 INCLUSIVE, CARBON ATOMS, M IS A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM, BORON, BERYLLIUM, MAGNESIUM AND ZINC, AND N IS EQUAL TO THE VALENCE OF THE METAL M, IN ADMIXTURE WITH 1-OLEFINS WITH A POLYMER CONTAINING LEWIS BASE GROUPS HAVING PRESENT THEREIN ATOMS SELECTED FROM THE GROUP CONSISTING OF OXYGEN, SULFUR, SELENIUM, NITROGEN, PHOSPHORUS, AND ARSENIC, SAID POLYMER BEING IMMISCIBLE WITH SAID ORGANOMETAL AND SAIL 1-OLEFINS; AND THEREAFTER SEPARATELY RECOVERING SAID 1-OLEFINS.
Claim 2
Dependent Claim
101 words
A PROCESS FOR SEPARATING ORGANOMETALS FROM 1-OLEFINS WHICH COMPRISES CONTACTING AN ORGANOMETAL HAVING THE FORMULA RNM, WHERE R IS AN ALKYL RADICAL CONTAINING FROM 2 TO 6 INCLUSIVE, CARBON ATOMS, M IS A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM, BORON, BERYLLIUM, MAGNESIUM AND ZINC, AND N IS EQUAL TO THE VALENCE OF THE METAL M, IN ADMIXTURE WITH 1-OLEFINS WITH A POLYMER CONTAINING LEWIS BASE GROUPS HAVING PRESENT THEREIN ATOMS SELECTED FROM THE GROUP CONSISTING OF OXYGEN, SULFUR, SELENIUM, NITROGEN, PHOSPHORUS, AND ARSENIC, SAID POLYMER BEING IMMISCIBLE WITH SAID ORGANOMETAL AND SAIL 1-OLEFINS; AND THEREAFTER SEPARATELY RECOVERING SAID 1-OLEFINS.
Claim 3
Dependent Claim
149 words
IN A PROCESS IN WHICH ETHYLENE IS REACTED WITH AN ORGANOMETAL HAVING THE FORMULA RNM, WHEREIN EACH R IS AN ALKYL RADICAL CONTAINING FROM 2 TO 6, INCLUSIVE, CARBON ATOMS, M IS A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM, BORON, BERYLLIUM, MAGNESIUM AND ZINC, AND N IS EQUAL TO THE VALENCE OF THE METAL M, SO AS TO FORM A MIXTURE OF AN RNM COMPOUND IN WHICH R IS AN ALKYL RADICAL CONTAINING NO BRANCHING NEARER THE METAL M THAN THE 3 POSITION, AND M AND N ARE AS DEFINED ABOVE, AND HIGHER 1-OLEFINS, THE IMPROVEMENT WHICH COMPRISES CONTACTING SAID MIXTURE OF AN RNM COMPOUND AND 1-OLEFINS WITH A POLYMER CONTAINING LEWIS BASE GROUPS HAVING PRESENT THEREIN ATOMS SELECTED FROM THE GROUP CONSISTING OF OXYGEN, SULFUR, SELENIUM, NITROGEN, PHOSPHORUS AND ARSENIC, THEREBY FORMING A COMPLEX OF SAID RNM COMPOUND WITH SAID POLYMER; AND SEPARATELY RECOVERING SAID 1-OLEFINS.
