The invention relates to strong hydrogen-bond acidic sorbents. The sorbents may be provided in a form that limits or eliminates intramolecular bonding of the hydrogen-bond acidic site between neighboring sorbent molecules, for example, by providing steric groups adjacent to the hydrogen-bond acidic site. The hydrogen bond site may be a phenolic structure based on a bisphenol architecture. The sorbents of the invention may be used in methods for trapping or detecting hazardous chemicals or explosives.

The present invention relates to a natural plant extract based ethylene absorber and a process for preparing the same for inhibiting the ripening process of fruits, vegetables and flowers in cold storages, warehouses and household refrigerators. The ethylene absorber comprises of emulsifier, herbal oil extract, water and anti-oxidant agent combined together in a synergistic ratio. The process for preparing ethylene absorber comprises the steps of preparing solution by mixing distilled herbal oil extract and emulsifier in a beaker; stirring the solution to form a homogenous mixture; preparing a solution by mixing D.I water and anti-oxidant agent; stirring and combining the mixture and solution to form a new solution; dipping molecular sieves in the solution; adding the mixture into solution; soaking the material in the solution for next 60 minutes; and pulling out the material from solution and drying it in air oven.

A method for separating mixed xylene includes steps that the mixed xylene is subjected to adsorption separation by means of an adsorbent having a metal organic framework material, so that one or more of xylene isomers are separated out. An organic ligand in the metal organic framework material is 2,5-dihydroxy-1,4-benzoquinone. Xylene isomers can be effectively separated using this method.

The present disclosure belongs to the technical field of extraction of fragrance substances, and specifically relates to Cymbidium goeringii balsam and a preparation method and use thereof. The present disclosure is implemented by cultivating multiple plants of Cymbidium goeringii with unravelling bloom collectively in a relatively small enclosed space, and enriching fragrance substances of Cymbidium goeringii in the air by lipid for adsorption. The method of the present disclosure can obtain Cymbidium goeringii balsam rich in a variety of fragrance components in a relatively short time. GC-MS detection indicates as many as 50 components. The present disclosure significantly improves the prior art in which only a small amount of fragrance components in Cymbidium goeringii can be extracted or even cannot be obtained. The present disclosure can be further used in extracting essential oils or applied directly.
