Abstract

An integrated process for making di-functional or multi-functional molecules with concurrent light paraffin upgrading is disclosed. The process involves three primary steps: (1) oxidation of an iso-paraffin to alkyl hydroperoxide and alcohol; (2) converting the alkyl hydroperoxide and alcohol to dialkyl peroxide; and (3) coupling functional molecules into di-functional or multi-functional molecules using the dialkyl peroxide as a radical initiator, while the dialkyl peroxide is converted to a tertiary alcohol. The functional molecules include any functional molecule R—X, where R is a hydrocarbyl group and X is a functional group such as —OH, —CN, —C(O)OH, —NH—, or the like.

First claim

1 . A process for making di-functional or multi-functional molecules, comprising:
(a) oxidizing a first feed stream comprising one or more iso-paraffins to form alkyl hydroperoxides and first tertiary alcohols; (b) catalytically converting the alkyl hydroperoxides and first alcohols to dialkyl peroxides; and (c) coupling a second feed stream using the dialkyl peroxides as a radical initiator to create di-functional or multi-functional molecules, while the dialkyl peroxides are converted to second tertiary alcohols.

2 . The process of claim 1 , wherein the first feed stream comprises iso-butane.

3 . The process of claim 1 , wherein the second feed stream comprises one or more functional molecules of the formula R—(CH 2 ) n —CHXY; wherein —X and —Y are independently selected functional groups; wherein R is selected from hydrogen, hydrocarbyl, or an independently selected functional group; and wherein n is an integer in the range of 0-30.

4 . The process of claim 3 , wherein the one or more functional groups are independently selected from halogens, —OH, —CN, —C(O)OH, —NH—, —SH, —NO 2 , —OSO 31 H, —OPO 3 H, or —OBOH.

5 . The process of claim 4 , wherein the halogens are selected from —F, —Cl, —Br, or —I.

6 . A process for making ethylene glycol, comprising:
(a) oxidizing a iso-butane to form t-butyl hydroperoxide and t-butyl alcohol; (b) catalytically converting the t-butyl hydroperoxide and the t-butyl alcohol to di-t-butyl peroxide; and (c) coupling methanol into ethylene glycol using the di-t-butyl peroxide as a radical initiator, while the di-t-butyl peroxide is converted to t-butyl alcohol.

7 . A process for making succinic acid, comprising:
(a) oxidizing a iso-butane to form t-butyl hydroperoxide and t-butyl alcohol; (b) catalytically converting the t-butyl hydroperoxide and the t-butyl alcohol to di-t-butyl peroxide; and (c) coupling acetic acid into succinic acid using the di-t-butyl peroxide as a radical initiator, while the di-t-butyl peroxide is converted to t-butyl alcohol.

8 . A process for making succinonitrile, comprising:
(a) oxidizing a iso-butane to form t-butyl hydroperoxide and t-butyl alcohol; (b) catalytically converting the t-butyl hydroperoxide and the t-butyl alcohol to di -t-butyl peroxide; and (c) coupling acetonitrile into succinonitrile using the di-t-butyl peroxide as a radical initiator, while the di-t-butyl. peroxide is converted to t-butyl alcohol.

9 . A process for making ethylene diamine, comprising:
(a) oxidizing a iso-butane to form t-butyl hydroperoxide and t-butyl alcohol; (b) catalytically converting the t-butyl hydroperoxide and the t-butyl alcohol to di-t-butyl peroxide; and (c) coupling methyl amine into ethylene diamine using the di-t-butyl peroxide as a radical initiator, while the di-t-butyl peroxide is converted to t-butyl alcohol.

10 . A process for making 1,2-dinitroethane, comprising:
(a) oxidizing a iso-butane to form t-butyl hydroperoxide and t-butyl alcohol; (b) catalytically converting the t-butyl hydroperoxide and the t-butyl alcohol to di-t-butyl peroxide; and (c) coupling nitromethane into 1,2-dinitroethane using the di-t-butyl peroxide as a radical initiator, while the di-t-butyl peroxide is converted to t-butyl alcohol.

11 . A process for making 1,2-dichloroethane, comprising:
(a) oxidizing a iso-butane to form t-butyl hydroperoxide and t-butyl alcohol; (b) catalytically converting the t-butyl hydroperoxide and the t-butyl alcohol to di-t-butyl peroxide; and (c) coupling methyl chloride into 1,2-dichloroethane using the di-t-butyl peroxide as a radical initiator, while the di-t-butyl peroxide is converted to t-butyl alcohol.
