The mechanism of the reaction of diethyl disulfide with natural rubber has been reported in detail in the literature. However, due to the shortcomings of traditional methods, people are constantly exploring new research methods. Since the 1980s, the model compound (MCV) method (the model compound means that the molecular structure is similar to the real rubber molecule, but the size is small. ), with the help of HPLC (high performance liquid chromatograph) Tapno mapaliiw ti krus-naisinggalut a prekursor ken pattapattaen ti sumaganad a pannakaporma ti modelo ti panagsilpo ti asupre . Nupay kasta, gapu ta dagiti nadumaduma a panagtangken a reaksion ti MCV ket mapasamak iti isu met laeng a panawen, narigat a mapaliiw dagiti dalan ti sungbat a dagiti indibidual a paset ket sumurot iti..
Tapno maparmek daytoy a parikut, idi tengnga ti 1990s, ti Nieuwenhuizen a grupo ti panagsukisok ti Unibersidad ti Leiden ket nangaramidda ti baro a pamay-an tapno adalen dagiti nababa a relatibo a molekular a dagsen a modelo a kompuesto ken dagiti immun-una a banag ti asupre-a naglaon ti krus-a panagsilpo iti sidong ti kondision ti simulado a bulkanisasion, tapno makaawat ti kemikal a naipalgak babaen ti panagkuenta babaen ti panagkuenta babaen ti panagkuenta, a nagpadagus a kas ti panagkarkrona, a nagpadagus a kas ti panagkarkrona a kas ti panagkarkrona, a nagipadaan ti maysa a panagkarkrona a kas ti panagkarkrona, ti panagkalkula ti maysa a panagkalkula, ti panagkalkula ti maysa a panagkalkula, ti panagkalkula ti maysa a panagkalkula ti maysa a panagkalkal. of homogeneous catalytic reactions during vulcanization, including precursor formation, desulfurization, degradation and sulfur crosslinking, of the zinc disulfide (ZDMC) and thiol-thiazole zinc salts (ZMBT). The uniqueness of the study is: (1) using quantum chemical calculation and matrix-assisted laser desorption ionization mass spectrometer, the first theoretically and Iti eksperimental a napasingkedan ti kaadda ti tengnga dagiti zinc disulfide complexes. iti napaut a panawen, naipagarup a dagiti nabaknang iti asupre a zinc promoter complexes iti proseso ti vulcanization ket addaan iti sentro nga akem iti proseso ti vulcanization, nga isu daytoy, tapno mapaandar ti ground state sulpur, tapno mapalaka ti panagsinnukat ken panagiyakar dagiti s atoms bayat dagiti goma a vulcanization, to infilfied the {Cros1" 3 a pakaammo ti panagsinnukat ti 2000 a panagporma ti PORT-CROVERS. However, the rich S-amino acid zinc disulfide complexes are active and can quickly release the connected S to an appropriate s-receptive body, so the usual spectral technique does not detect its existence. A matrix-assisted laser desorption ionization mass spectrometer was used to treat the isolated complexes in a vacuum environment (preventing s atom conversion or loss), and the results detected that the complex could be enriched to four s atomo.
