Abstract: The present invention relates to a composition of branched fatty acids or esters thereof, the process for preparing such a composition and its use in various industrial fields, such as in lubricant, in cosmetics and in home care. More particularly, the present invention relates to a composition comprising at least 30% by weight of polybranched C10-C24 fatty acids or esters thereof, and a cyclic compound content ranging from 1% to 8% by weight, the weight percentage being given on the total weight of the composition.

Abstract: A process to make propylene can include providing a reaction zone containing a catalyst and introducing a feedstock into the reaction zone. The catalyst can be an acid. The feedstock can include ethylene, dimethyl ether or methanol and dimethyl ether with at least 1000 wppm of dimethyl ether, and optionally steam. The feedstock can be contacted with the catalyst at temperature and pressure conditions to produce an effluent, including propylene, hydrocarbons, steam, optionally unconverted methanol and/or unconverted dimethyl ether and optionally unconverted ethylene. The temperature at the inlet of the reaction zone can be under 280° C., such as from 50 to 280° C. The effluent can be sent to a fractionation zone to recover propylene, optionally methanol, dimethyl ether and optionally ethylene. At least a part of methanol, dimethyl ether, and ethylene can be recycled to the reaction zone at step b).

Abstract: The present invention is a process to make propylene comprising: a) providing a reaction zone containing a catalyst; b) introducing a feedstock comprising ethylene, dimethyl ether or methanol and dimethyl ether comprising at least 1000 wppm of dimethyl ether, optionally steam into said reaction zone and into contact with said catalyst; c) operating said reaction zone at temperature and pressure conditions to produce an effluent comprising propylene, hydrocarbons, steam, optionally unconverted methanol and/or unconverted dimethyl ether and optionally unconverted ethylene; d) sending the effluent of step c) to a fractionation zone to recover propylene optionally methanol and for dimethyl ether and optionally ethylene; e) optionally recycling at least a part of methanol and for dimethyl ether and optionally recycling at least a part of ethylene to the reaction zone at step b); wherein the catalyst is an acid and the temperature at the inlet of the reaction zone is under 280° C.
