The work aim is to develop a mechanism for modeling possible supramolecular structures in a flame and to demonstrate the such an approach efficiency for calculating fire hazard parameters. The characteristic temperatures pulsation in homologous series due to differences in molecules clustering mechanisms were chosen assupramolecular state features indicators. It is shown that flash and autoignition temperatures have a change pulsation in the n-alkanes homologous series, which is similar to  changes  in  melting  points  and  solubility  in  water. An  assumption  is  made  about  the clustering primary stage presence by the peroxide mechanism during the flame combustion occurrence with the formation of an oxygen bridge between molecules, which is similar to solubility in water. It is shown that fire hazard parameters can depend both on the smallest cluster  length  and  on  the  associated  oxygen  molecules  number  during  the  combustion initiation.The  n-alkanes  aggregation  proportions  into  clusters  with  the  oxygen  molecules participation  have  been  determined,  which  allow  us  to  describe  the  critical  conditions  for the  combustion  initiation  with  the  sufficient  convergence:  lower  and  upper  flammability limits,  lower  and  upper  detonation  limits,  the  stoichiometric  concentration,  the  cold  flame upper  limit.  A  formula  was  developed  for  the  n-alkanes  autoignition  temperatures predictingbased on the \"ease of melting\" indicator, which works with R=0.98. It is shown that  supramolecular  peroxide  structures  formed  during  the  combustion  initiation  have easier  conditions  for  the  condensation.It  is  calculated  that  the  expected  corresponding characteristic  temperatures  of  peroxide  clusters  phase  transitions  can  be  realized  in  a flame.The  condensation  processes  participation  during  combustion  determines  the  flame front minimum thickness for the single peroxide-polymer structure formation.Key  words:hydrocarbons,   characteristic   temperatures,   cluster,   structure, length, peroxide proportion, fire hazard.<\/jats:p>","DOI":"10.31731\/2524.2636.2024.8.2.133.146","type":"journal-article","created":{"date-parts":[[2025,4,2]],"date-time":"2025-04-02T12:29:46Z","timestamp":1743596986000},"source":"Crossref","is-referenced-by-count":0,"title":["STUDY OF THE SUPRAMOLECULAR STRUCTURE INFLUENCE ON HYDROCARBONS FIRE HAZARD PARAMETERS"],"prefix":"10.52363","volume":"8","author":[{"name":"National University of Civil Protection of Ukraine","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1821-822X","authenticated-orcid":false,"given":"Dmytro","family":"TREGUBOV","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2497-7396","authenticated-orcid":false,"given":"Flora","family":"TREGUBOVA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"National University of Civil Protection of Ukraine","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"30103","published-online":{"date-parts":[[2024]]},"container-title":["Emergency Situations: Prevention and Liquidation"],"original-title":["\u0414\u041e\u0421\u041b\u0406\u0414\u0416\u0415\u041d\u041d\u042f \u0412\u041f\u041b\u0418\u0412\u0423 \u041d\u0410\u0414\u041c\u041e\u041b\u0415\u041a\u0423\u041b\u042f\u0420\u041d\u041e\u0407 \u0411\u0423\u0414\u041e\u0412\u0418 \u041d\u0410 \u041f\u0410\u0420\u0410\u041c\u0415\u0422\u0420\u0418 \u041f\u041e\u0416\u0415\u0416\u041d\u041e\u0407 \u041d\u0415\u0411\u0415\u0417\u041f\u0415\u041a\u0418 \u0412\u0423\u0413\u041b\u0415\u0412\u041e\u0414\u041d\u0406\u0412"],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T20:08:05Z","timestamp":1745525285000},"score":1,"resource":{"primary":{"URL":"https:\/\/fire-journal.ck.ua\/index.php\/fire\/article\/view\/211"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2024]]},"published-print":{"date-parts":[[2024]]}},"URL":"https:\/\/doi.org\/10.31731\/2524.2636.2024.8.2.133.146","relation":{},"ISSN":["2524-2636"],"issn-type":[{"type":"print","value":"2524-2636"}],"subject":[],"published":{"date-parts":[[2024]]}}}
