    摘要： This invention relates to a topical composition for treating amino acid based substrates comprising a protected thiol compound having the formula R—(S—Pr)m where R is a functional group, S is sulfur, and Pr is a heterocyclic protecting group, and m is an integer between 1 and 100. The invention further relates to systems which comprise this protected thiol compound and an activating mechanism. The protected thiol compounds of the present invention may be used in hair care compositions, textile care compositions, cosmetic compositions, oral care compositions, skin care, nail care, laundry care, acne care and animal care compositions. A preferred embodiment of the present invention provides a silicone composition and method for making. The composition comprises a polysiloxane or silicone resin, at least one linker, and at least one molecular hook.

    摘要： A method for the removal of nitrogen compounds from FCC feed or from catalytically cracked distillates including FCC cycle oils by using formaldehyde to selectively couple organic heterocyclic nitrogen species in the FCC feed or FCC distillate to form higher boiling coupling products out of the boiling range of FCC distillate. Removal of the nitrogenous compounds improves the operation of subsequent hydrodesulfurization steps needed for the distillate fraction to conform to low sulfur standards. The formaldehyde is preferably used in the form of paraformaldehyde. The reaction between the nitrogenous compounds in the cycle oil fraction with the formaldehyde is conveniently carried out in the cycle oil pumparound circuit of the FCC main column.
