摘要:
Novel polypeptides which promote the release of growth hormone when administered to animals are described. These polypeptides have the formula:A.sub.1 --D.sup..beta. Nal--A.sub.3 --Trp--A.sub.5 --A.sub.6 --Zwherein A.sub.1, A.sub.3, A.sub.5, A.sub.6 and Z" are as defined in the specification.
摘要:
Disclosed is a process for preparation of an amino acid, such as phenylalanine, with a high degree of optical purity. The process makes use of the same amino acid as a chiral template.

摘要:
Provided are 3-oxoadipate esters of certain polyols which are useful as crosslinkers in thermosetting coating compositions. Also provided are such thermosetting compositions comprised of a curable hydroxyl-functional polymer such as a polyester or acrylic and the crosslinkers of the present invention. Such compositions offer a significant improvement in curing temperature.
摘要:
A process for producing alpha-tocopherol from non-alpha-tocopherols comprising reacting the tocopherol with formaldehyde, carrying out the reaction at a temperature of at least about 175.degree. C. in the presence of a catalytic amount of an acidic ion exchange resin and subjecting the reaction mixture to catalytic hydrogenation.
摘要:
This invention relates to the dehydrogenation of a 3-.beta.-hydroxy steroid or a mixture of soy sterols to form the corresponding mixture of .DELTA..sup.4 -3-keto derivatives of phytosterols, the improvement which comprises dehydrogenating the steroid or mixture of sterols using an activated non-pyrophoric nickel catalyst and carrying out the oxidation in the presence of a diaryl ketone. One such process uses a non-pyrophoric Raney nickel type catalyst and a diaryl ketone, such as benzophenone as a hydrogen acceptor.
摘要:
Provided are curable copolymers having 1,3-dioxolan-2-one-4-yl groups incorporated therein. The copolymers are useful as binders in coating compositions and can be cured with primary amine cross-linking compounds to form a continuous polyurethane coating.
